The title compound was prepared by combining (1R,2R)—N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-phenylcyclopropanecarboxamide (8E, 0.08 g, 0.245 mmol) and the 1-(piperidin-4-yl)urea hydrochloride (0.088 g, 0.490 mmol) in NMP (0.816 ml) and heating the mixture 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 40-60% preparatory HPLC (ACN/MeOH)/H2O+0.01% TFA). Lyophilization of the combined fractions gave 63 mg (59%) of the titled compound as a yellow solid. 1H NMR (DMSO-d6) δ: 10.95 (s, 1H), 7.24-7.35 (m, 3H), 7.14-7.24 (m, 3H), 6.08 (s, 3H), 4.24 (d, J=13.1 Hz, 2H), 3.66 (br. s., 2H), 3.17 (dd, J=23.7, 12.1 Hz, 2H), 2.39-2.47 (m, 1H), 2.26-2.38 (m, 4H), 1.90 (d, J=13.1 Hz, 2H), 1.34-1.59 (m, 4H); ESI-MS: m/z 433.0 (M+H)+.
