Procedure

(S)-2-Trityloxymethyl-oxirane (636 mg, 2 mmol) and 2,2-dimethyl-propionic acid (3S,4S)-3-methyl-piperidin-4-yl ester (17, 400 mg, 2 mmol) are dissolved in 7 ml of ethanol and stirred at room temperature for 23 h. The white suspension is heated to 40° C. and stirred for additional 2 h. The reaction mixture is evaporated under reduced pressure and the crude product is purified by Flash-chromatography. (silica gel, 20% ethyl acetate in cyclohexane).
