実験手順

Trifluoromethanesulfonic acid (5.95 ml, 36.3 mmol) is added dropwise at -30° C. to a mixture of dichloromethane (130 ml) and pyridine (3.19 g, 40.3 mmol). Compound 12 (8.95 g, 40.3 mmol) in dichloromethane (60 ml) is then added dropwise at -25° C. The mixture is allowed to come to room temperature and is concentrated in vacuo, and the residue is chromatographed (hexane/ethyl acetate 6:1). Compound 13a (13 g, 91%) is obtained.
