The title compound was prepared by combining (1R,2R)—N-(7-chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-phenylcyclopropane carboxamide (8D, 0.1 g, 0.306 mmol) and the N-(piperidin-4-yl)acetamide (0.087 g, 0.612 mmol) in NMP (Volume: 1.020 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 45-65% preparatory HPLC (MeCN/MeOH)/H2O+0.01% TFA). Lyophilization of the combined fractions gave 87 mg (66%) of the titled compound as a white solid. Melting point (190.2-231.1° C.). 1H NMR (DMSO-d6) δ: 10.95 (s, 1H), 7.91 (d, J=7.8 Hz, 1H), 7.23-7.37 (m, 3H), 7.12-7.24 (m, 3H), 6.08 (s, 1H), 4.30 (d, J=12.9 Hz, 2H), 3.88 (br. s., 1H), 3.16 (dd, J=24.3, 11.6 Hz, 2H), 2.39-2.47 (m, 1H), 2.25-2.38 (m, 4H), 1.89 (d, J=13.6 Hz, 2H), 1.82 (s, 3H), 1.46-1.62 (m, 3H), 1.40 (ddd, J=8.2, 6.4, 4.0 Hz, 1H); [α]D20=+218° (C=0.6917, MeOH). ESI-MS: m/z 433.0 (M+H)+. Melting point (190.2-231.1° C.).
