Procedure

To a solution of (4-(5-(azidomethyl)-3-methylisoxazol-4-yl)-1-methyl-1H-pyrazol-3-yl)(4-chlorophenyl)methanone (0.03 g, 0.08 mmol) in anhydrous THF (10 mL), was added triphenylphosphine (32 mg, 0.12 mmol) at room temperature. The mixture was stirred for 12 h at room temperature. The mixture was concentrated and the residue was purified by flash chromatography eluting with (petroleum ether/ethyl acetate=1:3) to afford the title compound as a white solid (15 mg, 60% yield). LC/MS: m/z 312 [M+H]+; 1H NMR (300 MHz, CDCl3) δ 7.62 (d, J=9 Hz, 3H), 7.36 (d, J=9 Hz, 2H), 4.87 (s, 2H), 4.08 (s, 3H), 2.45 (s, 3H).
