Participants

Reaction Steps

A solution of N-(7-chloropyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2D, 200 mg, 0.604 mmol) and 1-(1,4-diazepan-1-yl)ethanone (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 (182.5 mg, 70%). 1H NMR (METHANOL-d4) δ: 7.89-7.99 (m, 6H), 7.62-7.68 (m, 4H), 7.34 (d, J=8.6 Hz, 2H), 6.26 (t, J=2.3 Hz, 2H), 4.47 (t, J=5.7 Hz, 2H), 4.18-4.30 (m, 2H), 4.05 (dt, J=16.2, 6.0 Hz, 4H), 3.82 (dt, J=11.6, 5.8 Hz, 4H), 3.67 (dt, J=8.7, 6.0 Hz, 4H), 2.19 (t, J=5.9 Hz, 2H), 2.13 (s, 3H), 2.03-2.11 (m, 2H), 1.90 (s, 3H), 1.56 (s, 12H). ESI-MS: m/z 437.1 (M+H)+.
