Reaction Steps

A suspension of 47 mg of ethyl rac-cis-5-{3-[2-(4-fluorophenyl)oxazol-4-ylmethoxy]cyclohexyloxymethyl}-2-methylbenzoate 24, 2 ml of 1,1-dimethylethanol and 50% (w/w) potassium hydroxide was heated at 85° C. (oil bath) for 2 hours. The pH was adjusted to 3 using dilute hydrochloric acid and the mixture was extracted twice with MTBE. The extracts were dried over magnesium sulfate, filtered and concentrated on a rotary evaporator, and the product was then purified by chromatography. This gave the product 20 of molecular weight 439.49 (C25H26FNO5); MS (ESI): 440 (M+H+).
