Procedure

A mixture of 2-[4-(4-amino-2-fluoro-phenyl)-piperazin-1-yl]-N,N-diethyl-2-phenyl-acetamide (0.30 mmol) and 4-isocyanato-3,5-dimethyl-isoxazole (1.0 mmol) in DCE (10 mL) was stirred at rt for 16 h. The solid that had formed was collected by filtration and dried under vacuum to give the title compound (100 mg, 64%). MS (ESI): mass calcd. for C28H35FN6O3, 522.28. m/z found, 523.4 [M+H]+. 1H NMR (CDCl3): 8.60-8.40 (br s, 1H), 7.60-7.25 (m, 6H), 6.78-6.71 (m, 1H), 6.68-6.57 (m, 1H), 4.21 (s, 1H), 3.60-3.40 (m, 2H), 3.39-3.15 (m, 2H), 2.95-2.45 (m, 8H), 2.24 (s, 3H), 2.13 (s, 3H), 1.11 (t, J=7.1, 3H), 1.05 (t, J=7.1, 3H).
