実験手順
A solution of 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-5-bromo-8-chloro-7-(1,4-dimethyl-1H-1,2,3-triazol-5-yl)-3,4-dihydroisoquinolin-1(2H)-one (293i, 76 mg, 0.13 mmol) in dichloromethane (4 mL) was cooled in an ice-water bath. Trifluoroacetic acid (6 mL) was added, and the mixture stirred and allowed to warm to room temperature overnight. After removal of the volatiles under vacuum, the residue was purified by silica gel chromatography (eluting with 10:1 dichloromethane/methanol) to give 5-bromo-8-chloro-2-[(4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl]-7-(1,4-dimethyl-1H-1,2,3-triazol-5-yl)-3,4-dihydroisoquinolin-1(2H)-one (Example 293, 56.9 mg, 90% yield) as a white solid). 1H NMR (400 MHZ, Methanol-d4): δ 7.79 (s, 1H), 6.10 (s, 1H), 4.75 (s, 2H), 3.84 (s, 3H), 3.59 (t, J=6.2 Hz, 2H), 3.07 (t, J=6.2 Hz, 2H), 2.30 (s, 3H), 2.24 (s, 3H), 2.16 (s, 3H). MS: 492 [M+1].
