Reaction Steps

A solution of N-(7-chloropyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2D, 50 mg, 0.151 mmol) and (R)—N,N-dimethylpyrrolidin-3-amine (34 mg, 0.302 mmol) in NMP (0.950 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, 10-35% (MeCN/H2O gradient+0.01% TFA). Lyophilization of the combined fractions gave the titled compound as a white solid (60 mg, 97%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.45 (s, 6H) 2.22-2.35 (m, 2H) 2.90 (d, J=3.79 Hz, 6H) 3.78-3.91 (m, 1H) 4.01-4.16 (m, 2H) 4.35 (d, J=6.57 Hz, 2H) 6.26 (d, J=2.27 Hz, 1H) 7.15 (s, 1H) 7.60 (d, J=8.34 Hz, 2H) 7.99 (d, J=8.34 Hz, 2H) 8.04 (d, J=2.27 Hz, 1H) 9.88 (br. s., 1H) 10.77 (s, 1H). ESI-MS: m/z 409.3 (M+H)+.
