164148-92-9, tert-Butyl 6-amino-3,4-dihydroisoquinoline-2(1H)-carboxylate is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
ferf-Butyl 6-amino-3,4-dihydroisoquinoline-2(1 H)-carboxylate (0.500 g, 2.01 mmol), methyl 2-(2-(2-(2-(methylsulfonyl)-5-(trifluoromethyl)pyrimidin-4- yl)ethyl)phenyl)acetate (166) (0.675 g, 1.68 mmol), trifluoroethanol (3 mL), and TFA (0.3 mL) were loaded into a microwave tube, sonicated for two minutes, then heated under microwave irradiation at 100 C for 20 minutes. The cooled mixture was concentrated, co-evaporated with toluene (3x 20 mL) and loaded onto a 10 g SCX cartridge in methanol. The cartridge was eluted with methanol (200 mL), then with 1 % methanolic methylamine (200 mL). The methanolic methylamine eluent was concentrated to give a brown oil (0.850 g). The oil was dissolved in DCM (5 mL), and Boc anhydride (549 mg, 2.52 mmol) was added. The resulting mixture was stirred under an oil bubbler for 18 hours, then diluted with DCM (50 mL) and washed with water (50 mL). The aqueous layer was extracted with DCM (2x 50 mL), and the combined DCM phases dried (phase separation filter) and evaporated.Chromatography (Isolera, 40 g silica cartridge, 0-50% ethyl acetate/petroleum benzine 40-60 C) gave the title compound (180) (520 mg, 54%) as a yellow syrup; 1H NMR (400 MHz, CDCI3) delta 8.54 (s, 1 H), 7.45 (s, 2H), 7.38 (s, 1 H), 7.28 – 7.18 (m, overlaps with CDC ), 7.10 (d, J = 8.5 Hz, 1 H), 4.56 (s, 2H), 3.75 (s, 2H), 3.70 – 3.62 (m, 5H), 3.17 – 3.03 (m, 4H), 2.85 (t, J = 5.6 Hz, 2H), 1.50 (s, 9H). LCMS Method C: H 6.93 min; m/z 571 .1 {M+H] +, m/z 515.0 [M+tBu+2H] +.
164148-92-9, As the paragraph descriping shows that 164148-92-9 is playing an increasingly important role.
