Participants

Reaction Steps

365 mg of tert-butyl 4-(cis-3-hydroxycyclohexyl)-2,2-dimethylbutyrate are, together with 850 mg of 4-iodomethyl-5-methyl-2-(4 methylphenyl)oxazole, dissolved in 5 ml of dimethylformamide, and 110 mg of sodium hydride (60% strength in paraffin) are added. After 1 hour of stirring at room temperature, 100 ml of methyl tert-butyl ether are added and the reaction mixture is washed three times with water. The organic phase is dried over MgSO4 and the solvent is then removed under reduced pressure. The residue is purified by RP-HPLC. This gives 330 mg of tert-butyl 2,2-dimethyl-4-[cis-3-(5-methyl-2-p-tolyloxazol-4-ylmethoxy)cyclohexyl]butyrate as a white solid. C28H41NO4 (455.64), MS(ESI): 456 (M+H+).
