Procedure

To a cold solution (below 0° C.) of 7-bromoisoquinolin-3-amine (20 g, 0.09 mol) in pyridine (150 mL) was added cyclopropanecarbonyl chloride (11.2 g, 0.108 mol) dropwise. The mixture was stirred at room temperature overnight. After water (500 mL) was added, the reaction mixture was stirred for 30 min. Solid was collected by filtration and washed with water to give the desired product (21 g, 80.4%). LCMS (ESI): RT (Min)=1.009, M+H+=290.7, method=A. 1H NMR (400 MHz, DMSO-d6) δ 10.96 (s, 1H), 9.10 (s, 1H), 8.44 (s, 1H), 8.30 (s, 1H), 7.22 (d, J=8.8 Hz, 1H), 7.67 (d, J=8.8 Hz, 1H), 2.02-2.10 (m, 1H), 0.84-0.79 (m, 4H).
