Procedure
3-(2-chloro-6-fluorophenyl)-5-(1-(3-chlorophenyl)-5-(trifluoromethyl)-1H-pyrazol-4-yl)isoxazol-4-amine (example B-36) (40 mg, 0.1 mmol) was dissolved in formic acid (3 mL). The mixture was stirred at room temperature overnight. To the reaction mixture was added water. The resulting precipitate was collected, washed with water and dried under vacuum. The product was purified by pTLC (EE/PE 2:1) to give 32 mg of the desired product (example B-48) (yield 75%). Result of LC/MS MH+: 484.82; NMR (CDCl3): 6.63 (t, 1H), 7.22 (m, 1H), 7.38-7.59 (m, 6H), 8.02 (s, 1H) 8.22 (s, 1H)
