Procedure

A solution of N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2F, 86 mg, 0.25 mmol) and 4-methylpiperidine (77 mg, 0.75 mmol) in DMF (1.0 mL) was stirred at 100° C. for 2 h. After cooling to room temperature, the mixture was diluted with a few drops of DMSO and methanol, and was then purified by preparatory HPLC (45-45% MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a white solid (88.6 mg, 87%). Melting point (154.0-158.0° C.). 1H NMR (DMSO-d6) δ: 10.85 (s, 1H), 7.99 (d, J=8.3 Hz, 2H), 7.60 (d, J=8.6 Hz, 2H), 7.29 (s, 1H), 6.16 (s, 1H), 4.46 (d, J=12.1 Hz, 2H), 2.98-3.10 (m, 2H), 2.37 (s, 3H), 1.78 (d, J=12.9 Hz, 2H), 1.61-1.74 (m, 1H), 1.46 (s, 6H), 1.28-1.39 (m, 2H), 0.98 (d, 3H); ESI-MS: m/z 408.3 (M+H)+.
