EXAMPLE 8 In 100 ml of ice water was dissolved 10.6 g of 5-isoquinolinesulfonyl chloride hydrochloride, and the pH of the solution was adjusted to 6 with a saturated aqueous sodium hydrogencarbonate solution, followed by extraction with of 200 ml of dichloromethane. The dichloromethane layer was added dropwise to a 100 ml of dichloromethane solution containing 6.0 g of 3-hydroxypiperidine and 6.0 g of triethylamine over 30 minutes while cooling with ice. The mixture was stirred at a temperature of 15 C. to 20 C. for 3 hours, washed with water, and dried with anhydrous magnesium sulfate. Then, the dichloromethane was removed under reduced pressure to obtain 8.50 g of 1-(5-isoquinolinesulfonyl)-3-hydroxypiperidine.

D. 1-[(3,3-Dimethyl-3-silabutoxy)methyl]-5-(6-isoquinolyl)-2-(phenylsulfonyl)imidazole. To a solution of 6-bromoisoquinoline (73 mg, 0.35 mmol) in anhydrous DMF (0.75 mL) was added copper(II) oxide (28 mg, 0.35 mmol). The mixture was purged with nitrogen, tetrakis(triphenylphosphine)palladium(0) (55 mg, 0.048 mmol) was added, and then the materials were stirred at 100 C. for 5 minutes in a sealed vial. The vial was cooled to room temperature and then a solution of 5-(1,1-dibutyl-1-stannapentyl)-1-[(3,3-dimethyl-3-silabutoxy)methyl]-2-(phenylsulfonyl)imidazole (200 mg, 0.3.19 mmol) in anhydrous DMF (0.25 mL) was added. The mixture was purged with nitrogen then the sealed reaction was stirred at 105 C. for 8 hours. The reaction was cooled to room temperature, filtered through celite, and the celite rinsed with ethyl acetate. The filtrate was diluted with water, extracted three times with dichloromethane, and the organic layers combined. The organic solution was washed with brine, dried over anhydrous magnesium sulfate, filtered, and volatiles evaporated. The material was purified by chromatography on a normal phase silica gel column with 30 to 100% ethyl acetate in hexanes. Fractions containing clean product were combined and the solvent evaporated. The material was dried under vacuum at 60 C. to provide the title compound (1.2 g, 87%). MS (ESI) m/z 466.2 [M+1]+.

As the paragraph descriping shows that 34784-05-9 is playing an increasingly important role.

General procedure: The desired alcohol intermediate (p83-86 as reported in the table, 1 eq) was dissolved in THF (-40 vol). PP (1.5 eq) was added, followed by the desired phenol (commercially available, 1.5 eq). The mixture was stirred at RT for 15′, then cooled to 0 C. DIAD (1.5 eq) was added dropwise and, after 10′, the ice bath was removed and the mixture was allowed to reach RT and stirred for at that temperature for 1.5-2.5 hrs. The mixture was concentrated and the crude obtained was purified by FC on silica gel and/or NH column (eluting mixture Cy/AcOEt) and/or C18 cartridge (eluent from water + 0.1 % formic acid / MeCN + 0.1 % formic acid) to afford the title compound.
