A suspension of intermediate 15 (275 mg; 1 mmol) in dichloromethane (10 ml) became homogeneous by addition of SOCl2 (2.3 ml) at room temperature. After 2 hours of stirring at room temperature, all the volatiles were removed under reduced pressure giving a yellow solid which corresponds to the expected intermediate 16 in quantitative yield (294 mg).
