Procedure

A solution of N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-(pyridin-4-yl)cyclopropanecarboxamide (7E, 100 mg, 0.305 mmol) and N-(piperidin-4-yl)acetamide (87 mg, 0.610 mmol) in NMP (1 mL) was stirred at room temperature 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 (10-40% MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a white solid (12 mg, 9%). 1H NMR (DMSO-d6) δ: 10.98 (s, 1H), 8.45 (d, J=5.8 Hz, 2H), 7.90 (d, J=7.8 Hz, 1H), 7.27 (s, 1H), 7.20 (d, J=6.1 Hz, 2H), 6.08 (s, 1H), 4.28 (br. s., 2H), 3.88 (br. s., 2H), 3.15 (d, J=3.0 Hz, 2H), 2.40-2.47 (m, 2H), 2.30-2.37 (m, 3H), 1.85-1.96 (m, 2H), 1.81 (s, 3H), 1.46-1.62 (m, 3H). ESI-MS: m/z 434.0 (M+H)+.
