Procedure

A solution of the compound of Example 263 (0.4 g) and 1 mL thionyl chloride in 6 mL CH2Cl2 was refluxed for 1 h, then cooled and poured into ice-water. Additional CH2Cl2 was added. The organic layer was separated, washed with brine, dried and concentrated. Flash chromatography of the residue with 5% ethyl acetate-hexane as eluent gave 0.4 g of the desired product as a white solid. m.p. 68°-72° C.
