Reaktionsschritte
To a solution of 2,2-difluoro-2-phenylthioacetamide (1.57 g, 0.0092 mol) in 95% ethanol (20 mL) was added α-bromo-4-acetylpyridine hydrobromide (3.20 g, 0.012 mol) and the mixture warmed on a steam bath for thirty minutes. The product was isolated in the usual way and recrystallized from ethyl acetate/hexane to afford 1,1-difluoro-1-phenyl-[4-(4-pyridyl)-2-thiazolyl]methane (1.27 g, 48%). mp. 54.5°-55.5° C.
