Procedure

A mixture of (S)-2-(4-phenoxyphenyl)-7-(piperidin-4-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide (1.26 g, 3.03 mmol), (E)-4-(4-(2-((tert-butoxycarbonyl)amino)ethyl)piperazin-1-yl)but-2-enoic acid (948.4 mg, 3.03 mmol), HATU (1.21 g, 3.18 mmol), DIEA (782 mg, 6.06 mmol) in 30 mL of DMF was stirred at RT for 15 hr. The mixture was poured into 300 mL of water and extracted with EA (100 mL). The organic phase was washed with water (100 mL×3) and concentrated to give 1.25 g (58%) of product as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 7.50 (d, J=8.4 Hz, 2H), 7.42 (t, J=8.4 Hz, 2H), 7.17 (t, J=7.4 Hz, 1H), 7.12-7.02 (m, 4H), 6.67 (br s, 1H), 6.64-6.53 (m, 3H), 4.53-4.40 (m, 1H), 4.14-4.05 (m, 1H), 3.32-3.25 (m, 2H), 3.10-2.91 (m, 5H), 2.45-2.15 (m, 1H), 2.10-2.00 (m, 1H), 1.96-1.84 (m, 1H), 1.78-1.65 (m, 1H), 1.62-1.50 (m, 1H), 1.37 (s, 9H), 1.31-1.10 (m, 3H). MS (ESI) m/e [M+1]+713.0.
