Procedure

N-(7-Chloropyrazolo[1,5-a]pyrimidin-5-yl)-4-(2-hydroxypropan-2-yl)benzamide (2D) (1.0 equivalent) and morpholine (2.0 equivalent) were dissolved in dry n-butanol (0.1 M) under nitrogen. The mixture was heated to 100° C. for 18 h. Next day, lower temperature to room temperature, and product precipitates. The precipitate was collected by filtration and then washed with diethyl ether to give the titled compound (54%) as a pink solid. Melting point (225.0-229° C.). 1H NMR (400 MHz, MeOD) δ ppm 3.31 (s, 6H) 3.70-3.79 (m, 4H) 3.90-3.98 (m, 4H) 6.35 (d, J=2.27 Hz, 1H) 7.40 (s, 1H) 7.66 (d, J=8.59 Hz, 2H) 7.94 (d, J=8.59 Hz, 2H) 8.01 (d, J=2.27 Hz, 1H). ESI-MS: m/z 382.2 (M+H)+.
