Water → 1-{1-[(4-Cyclohexylphenyl)carbonyl]azetidin-3-yl}-4-(phenylcarbonyl)-piperazine

To a solution of compound 1j (0.08 g, 0.24 mmol) and HATU (0.093 g, 0.24 mmol) in DMF (3 mL) was added DIPEA (0.1 mL). The mixture was stirred at room temperature for 30 min, and then compound 1k (0.03 g, 0.25 mmol) was added to the mixture. The reaction mixture was stirred at room temperature for 18 h. Water (6 mL) was added to the mixture. The mixture was extracted with EtOAc (2×6 mL). The organic layer was dried over MgSO4, filtered, and concentrated. The crude compound 1 was purified by reverse phase chromatography. 1H NMR (300 MHz, CD3OD): δ 7.58 (d, 2H), 7.44-7.53 (m, 5H), 7.34 (d, 2H), 4.6 (m, 1H), 4.42 (m, 2H), 4.27 (m, 1H), 3.85 (m, 5H), 3.05 (m, 4H), 2.57 (m, 1H), 1.85 (m, 5H), 1.45 (m, 5H). MS m/z (M+H+) 432.3.
