Some tips on 34784-06-0

As the paragraph descriping shows that 34784-06-0 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34784-06-0,7-Chloroisoquinoline,as a common compound, the synthetic route is as follows.

7-chloroisoquinoline (9 g, 55.0 mmol, 1.0 equiv)[mixture of 7-isoquinoline 3-5a and 8-isoquinoline 3-5b (a/b=3/2)]was dissolved in nitrobenzene (180 mL) and heated at 180 C. Bromine was added dropwise to this dark orange solution (3.11 ml, 60.5 mmol, 1.1 equiv.). The reaction mixture was stirred at 180 C. for 10 hours. LCMS showed that almost complete conversion. The reaction mixture was cooled to room temperature, 2M HCl in Et2O (30 mL) was added, followed by dilution with Et2O and Hexane. The precipitate was collected then taken up with EtOAc (200 mL), neutralized with saturated Na2CO3, and separated. The organic layer was dried over Na2SO4, filtered and concentrated. The crude residue was purified with silica gel chromatography (EtOAc/Hexane=0->30%) to give the title product 3-4. LRMS m/z (M+H) 242.2 found, 241.9 required., 34784-06-0

Downstream synthetic route of 34784-06-0

The synthetic route of 34784-06-0 has been constantly updated, and we look forward to future research findings.

34784-06-0, 7-Chloroisoquinoline is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: Dimethylsulfamoyl chloride (34; 0.144 mL, 1.34 mmol) was added to a solution of isoquinoline (5; 157 mg, 1.22 mmol) and 1H-indol-7-yl acetate (33; 213 mg, 1.22 mmol) in toluene (4 mL) at r.t. The mixture was concentrated to a thick but stirrable paste (1.5 mL), which was stirred at 50 C for 3 h. TLC and LCMS showed reaction was largely complete by this time. The mixture was diluted with EtOAc (40 mL), washed with H2O (40 mL) and sat. brine (20 mL), dried (Na2SO4), filtered and evaporated to dryness. The residue was purified by flash silica gel chromatography (loading in CH2Cl2) (eluent: gradient 20 to 50% EtOAc in heptane). Fractions containing the desired product were evaporated to afford the title compound 37a (208 mg, 42%) as a white solid, 34784-06-0

The synthetic route of 34784-06-0 has been constantly updated, and we look forward to future research findings.
