실험 절차

Benzyl bromide (2.05 g, 12 mmol) in THF (10 mL) was added dropwise over 15 minutes to a supension of sodium N,N-diethyldithiocarbamate trihydrate (2.25 g, 10 mmol) in 25 mL of THF at room temperature. The solution was allowed to stir at room temperature for 3 hours when the solids were filtered off and the filtrate concentrated. The crude residue was purified by column chromatography (silica gel, 20% ethyl acetate in petroleum spirits) to obtain the title compound (2.25 g, 94%). 1H-nmr (CDCl3) δ 1.3 (6H), 3.7 (2H), 4.1 (2H), 4.6 (2H), 7.3 (5H).
