Reaction Steps

(5RS)-3-(3-Fluoro-4(4-(2-acetoxyacetyl)piperazin-1-yl)phenyl)-5-isoxazol-3-yloxymethyl-4,5-dihydroisoxazole (112 mg, 0.25 mM) was suspended in a saturated solution of ammonia in methanol (8 ml), diluted with tetrahydrofuran (5 ml). The mixture was stirred at ambient temperature for 40 hours. The residue after evaporation was chromatographed on a 5 g silica Mega Bond Elut® column, eluting with a gradient from 0–5% methanol in dichloromethane. Relevant fractions were combined to give the desired product (92 mg).
