실험 절차

1-(2,2-Difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(6-methoxypyridin-3-yl)isoquinolin-3-yl)cyclopropanecarboxamide (100 mg, 0.210 mmol) was dissolved in a mixture of 1.2 mL of 1,4-dioxane and 0.6 mL of 4M aqueous hydrochloric acid. The solution was heated at 90° C. for 2 hours. The crude reaction mixture was quenched with one equivalent of triethylamine and was then evaporated to dryness. The crude product was partitioned between dichloromethane and water. The organic layer was separated, dried over sodium sulfate, and a portion of the material was purified on 12 g of silica gel utilizing a gradient of 0-10% methanol in dichloromethane to yield 1-(2,2-difluorobenzo-[d][1,3]dioxol-5-yl)-N-(1-(6-oxo-1,6-dihydropyridin-3-yl)isoquinolin-3-yl)cyclopropane-carboxamide as a white solid. ESI-MS m/z calc. 461.1. found 461.9 (M+1)+. Retention time 1.67 minutes.
