The resulting reaction mixture was allowed to stir at room temperature for 18 hours. The reaction mixture was then washed with 1N aqueous HCl (1×5 mL) and saturated aqueous NaHCO3 (1×5 mL). The organic layer was dried over sodium sulfate and evaporated to yield 1-(benzo[d][1,3]dioxol-5-yl)-N-(6-chloro-5-methylpyridin-2-yl)cyclopropanecarboxamide (120 mg, 71% over 2 steps). 1H NMR (400 MHz, DMSO-d6) δ 8.64 (s, 1H), 7.94-7.91 (m, 1H), 7.79-7.77 (m, 1H), 7.09 (m, 1H), 7.00-6.88 (m, 2H), 6.06 (s, 2H), 2.25 (s, 3H), 1.47-1.44 (m, 2H), 1.13-1.10 (m, 2H) ESI-MS m/z calc. 330.1. found 331.5 (M+1)+.
