Participants

Reaction Steps

A solution of N-(7-chloro-pyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2D, 200 mg, 0.604 mmol) and 2-(piperidin-4-yl)propan-2-ol (130 mg, 0.906 mmol) in Dioxane (6 mL) was stirred at 85° 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, 5-95% (MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a white solid (105 mg, 41%). 1H NMR (METHANOL-d4) δ: 8.00 (d, J=2.3 Hz, 1H), 7.95 (d, 2H), 7.66 (d, J=8.3 Hz, 2H), 7.39 (s, 1H), 6.33 (d, J=1.5 Hz, 1H), 4.59 (d, J=11.6 Hz, 2H), 2.97 (t, 2H), 1.95 (d, J=9.1 Hz, 2H), 1.61-1.69 (m, 3H), 1.56 (s, 6H), 1.21 (s, 6H). ESI-MS: m/z 438.0 (M+H)+.
