실험 절차

Two batches were prepared by the following method: a mixture of 5-amino-8-chloro-7-(1,4-dimethyl-1H-1,2,3-triazol-5-yl)-6-iodo-3,4-dihydroisoquinolin-1(2H)-one (293f, 2.9 g, 6.9 mmol each batch) and palladium on carbon (2.9 g) in glacial acetic acid (29 mL) and methanol (290 mL) was stirred under a hydrogen balloon at room temperature overnight. The combined reaction mixtures were filtered through celite, and the filter pad washed with methanol (300 mL). The filtrate was concentrated and the residue purified by silica gel chromatography (eluting with 10:1 dichloromethane/methanol) affording 5-amino-8-chloro-7-(1,4-dimethyl-1H-1,2,3-triazol-5-yl)-3,4-dihydroisoquinolin-1(2H)-one (293g, 3.6 g, 65% combined yield) as yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 8.12 (s, 1H), 6.82 (s, 1H), 3.75 (s, 3H), 3.29-3.28 (m, 2H), 2.70-2.67 (m, 2H), 2.07 (s, 3H). MS: 292 [M+1].
