Procedure

tert-Butyl 3-(3-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido)isoquinolin-1-yl)benzoate (603 mg, 1.11 mmol) was dissolved in dichloromethane (6 mL) and trifluoroacetic acid (3 mL). The reaction mixture was stirred at room temperature for 3.5 hours before it was evaporated to dryness to yield 3-(3-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamido) isoquinolin-1-yl)benzoic acid (499 mg, 75%) as the TFA salt. ESI-MS m/z calc. 488.1. found 489.1 (M+1)+. Retention time 2.06 minutes.
