Reaction Conditions

Reaction Steps

A solution of (5-methyl-oxazol-2-yl)-phenyl-methanone (intermediate 2) (3.0 g, 16 mmol) in 32 mL dry THF at 0° C. under nitrogen was treated dropwise over 10 min with a 2 M solution of cyclohexylmagnesium chloride in diethyl ether (10 mL, 20 mmol). The resulting deep yellow solution was stirred at 0° C. for about 30 min during which time a precipitate was formed, and then at RT for 1.5 h. The reaction mixture was cooled to 0° C. again and treated cautiously with satd. ammonium chloride solution (aq.). The mixture was stirred at RT for 10 min then diluted with water (10 mL). The phases were separated and the organic phase was washed with brine. The combined aqueous phase was extracted with DCM and the combined organic phase was dried (MgSO4) and concentrated in vacuo to give the crude product, which was triturated with ether, filtered off and dried.
