Reaction Steps

A solution of cyclopropylamine (0.52 mL, 0.43 g, 7.5 mmol) and triethylamine (1.4 mL, 1.01 g, 10.0 mmol) in CH2Cl2 (5 mL) was added to a suspension of 1H-pyrazole-4-carbonyl chloride (0.69 g, 5.3 mmol) in CH2Cl2 (20 mL) at 0° C. The reaction mixture was stirred overnight at room temperature. After evaporation of the solvent, the crude product was purified by MPLC using EtOAc on silica gel to give 0.79 g (99%) of a white solid as the title compound. 1H NMR (400 MHz, METHANOL-D4) δ 0.52-0.62 (m, 2 H), 0.72-0.82 (m, 2 H), 2.69-2.86 (m, 1 H), 7.91 (s, 1 H), 8.09 (s, 1 H).
