실험 절차

A solution of acetyl chloride (2.5 g) in 50 mL of acetonitrile was added dropwise to a solution of 9.8 g of 5-chloro-2-((2-((dimethylamino)methyl)phenyl)thio)benzyl alcohol (Example 2) in 25 mL of triethylamine and 200 mL of acetonitrile. The reaction mixture was stirred for 3 hr at room temperature, filtered and concentrated in vacuo to give a yellow oil. This oil was chromatographed on silica gel with EtOAc as the eluent. Concentration of solvents afforded 3.8 g (34% yield) of 5-chloro-2-((2-((dimethylamino)methyl)phenyl)thio)benzyl acetate as a light yellow oil. Upon standing, oil crystallized to a beige solid, m.p. 41°-44° C.
