Procedure

To a solution of thiazol (0.71 ml, 10 mmol) in dry THF (20 ml) was added dropwise 1.6 M-BuLi in hexane (6.9 ml, 11 mmol) under argon at -78° C. The reaction mixture was stirred at -78° C. for 0.5 hr and Bu3SnCl (3.1 ml, 11 mmol) was added dropwise. After stirring for 1 hr at -78° C. and for 1 hr at room temperature, the mixture was concentrated, triturated with water (50 ml) and extracted with diethylether (100 ml×3). The extract was washed with brine, dried and concentrated under reduced pressure to give (33) as colorless oil.(3.7 g, quant.).
