実験手順

0.5 g of 3-[2-(4-fluorophenyl)-5-methyloxazol-4-ylmethoxy]cyclohexanol is dissolved in 3 ml of pyridine and, at 0° C., 0.6 g of 3,5-dinitrobenzoyl chloride is added. The reaction mixture is then heated at 50° C. for 10 minutes. The reaction is checked (LCMS) showing the formation of the desired product, in addition to unreacted alcohol cis-3-[2-(4-fluorophenyl)-5-methyloxazol-4-ylmethoxy]cyclohexanol. After a further 10 minutes of stirring at room temperature, the reaction is terminated by addition of 5 ml of concentrated hydrochloric acid, and the crude product is filtered off with suction, taken up in ethyl acetate, washed with saturated sodium bicarbonate and sodium chloride solution and dried over magnesium sulfate. Purification by HPLC gives 0.15 g of the compound cis-3-[2-(4-fluorophenyl )-5-methyloxazol4-ylmethoxy]cyclohexyl 3,5-dinitrobenzoate as yellow solid.
