Reaction Steps

To a solution of 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-chloro-1-oxo-7-(propan-2-yloxy)-1,2,3,4-tetrahydroisoquinoline-5-carboxylic acid (90a, 17 mg, 0.033 mmol) in DMF (1 mL) was added triethylamine (0.023 mL, 0.165 mmol) and HATU (14 mg, 0.035 mmol). The reaction mixture was stirred for 5 minutes, and then dimethylamine.HCl (4.10 mg, 0.050 mmol) was added. The reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was diluted with H2O (5 mL) and the solid that precipitated was collected by filtration and dried under vacuum to give 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-chloro-N,N-dimethyl-1-oxo-7-(propan-2-yloxy)-1,2,3,4-tetrahydroisoquinoline-5-carboxamide (90b, 16 mg, 89% yield) as a white solid.
