Procedure

A solution of N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-phenylcyclopropanecarboxamide (8C, 200 mg, 0.612 mmol) and (R)-3-fluoropyrrolidine (109 mg, 1.22 mmol) in NMP (1.85 mL) was stirred at 100° C. overnight. After cooling to room temperature, the mixture was diluted with a few drops of DMSO and methanol, and was then purified by preparatory HPLC (35-40% MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a white solid (60 mg, 26%). 1H NMR (DMSO-d6) δ: 10.77 (s, 1H), 7.24-7.35 (m, 2H), 7.11-7.25 (m, 3H), 6.93 (s, 2H), 5.95 (s, 1H), 5.30-5.61 (m, 1H), 3.74-4.41 (m, 4H), 2.01-2.47 (m, 6H), 1.48 (dt, J=9.0, 4.7 Hz, 1H), 1.29-1.42 (m, 1H). ESI-MS: m/z 380.0 (M+H)+.
