Reaction Steps

To a solution of (4-(3-(4-chlorobenzoyl)-1-methyl-1H-pyrazol-4-yl)-3-methylisoxazol-5-yl)methyl acetate (0.3 g, 0.8 mmol) in THF (10 mL), was added NaOH solution (5 mL, 1 N in water). The mixture was stirred for 2 hours at 55° C. After cooling to room temperature, DCM (50 mL) was added and the layers separated. The separated organic layer was dried over anhydrous sodium sulfate and concentrated to afford the titled product as a yellow oil (0.2 g, 75% yield). LC/MS m/z 331 [M+H]+; 1H NMR (300 MHz, CDCl3) δ 8.13 (d, J=9 Hz, 2H), 7.45 (d, J=9 Hz, 3H), 4.62 (s, 2H), 4.07 (s, 3H), 2.15 (s, 3H).
