Procedure

3-(2-chloro-6-fluorophenyl)-5-(1-(3-chlorophenyl)-5-(trifluoromethyl)-1H-pyrazol-4-yl)isoxazole-4-carboxylic acid (50 mg, 0.0001 mmol), Morpholine (9 mg, 0.0001 mmol), HOBt (14 mg, 0.0001 mmol) and EDCI (19 mg 0.00012 mmol) were dissolved in 1 mL dry DMF. N-Methylmorpholine (100 NL, 0.001 mmol) was added and the reaction mixture was stirred at room temperature overnight. Morpholine, HOBt, EDCI and N-Methylmorpholine were added again in the aforementioned ratios. The mixture was stirred at room temperature for 24 h. DMF was removed by evaporation. An aqueous solution of 5% citric acid was added. The precipitate was filtered and dried. The product (example B-35) was purified by pTLC (PE/EE 5/5) to give 26 mg of a yellow oil (yield 45%). Result of LC/MS MH+: 554.7; 1H NMR (CDCl3): 8.15 (1H, s, CH-pyraz.), 7.35-7.6 (6H, m, CH-arom), 7.15 (1H, t, CH-arom), 3.6 (4H, m, CH2-morpholine), 3.18 (4H, m, CH2-morpholine).
