Reaction Steps

(5RS)-3-(3,4-Difluorophenyl)-5-isoxazol-3-yloxymethyl-4,5-dihydroisoxazole (140 mg, 0.5 mM) was treated with 1,2,4-triazole using essentially the conditions of Example 5. Crude product was chromatographed on a 5 g silica Mega Bond Elut® column, eluting with a gradient from 0–25% ethyl acetate in dichloromethane. Relevant fractions were combined to give the desired product (45 mg). MS (ESP): 330 (MH+) for C15H12FN5O3
