Procedure

A mixture of 60c (1.4 g, 4.8 mmol) and SnCl2.2H2O (4.9 g, 21.7 mmol) in EtOH (50 mL) was stirred at 80° C. After 4 h, the mixture was cooled to room temperature and was slowly added to saturated aqueous NaHCO3. The solid was filtered and washed with H2O. The solid was triturated with EtOAc and the filtrate was concentrated. The crude product 60d was used in the next reaction without purification. MS m/z (M+H+) 261.1.
