Reaction Steps

A suspension of sodium hydride in mineral oil (0.44 g of 60%) in anhydrous DMF (10 mL) was cooled to 0° C. N-[4-(4-hydroxyphenyl)butyl]phthalimide (2.95 g, 10 mmol) dissolved in dry DMF (15 ml) was added into the mixture which was then stirred for 30 min at 0° C. and allowed to warm to room temperature over 1 h. To the mixture was added portionwise NAN-dimethylthiocarbamoyl chloride (1.35 g, 11 mmol) dissolved in DMF (10 ml). The newly formed mixture was stirred at room temperature overnight, then at 50° C. for 1 h, and was cooled back to room temperature, at which point methanol (10 mL) was added into the mixture. The solvent was removed under reduced pressure. The residue was purified by flash chromatography over silica gel (dichloromethane/hexane/ethyl acetate, 10:1:0.2, v/v) to give N-{4-[4-(dimethylhiocarbamoyloxy)phenyl]butyl}phthalimide 34 (2.27 g, 59%) as a slightly yellow solid. 1H NMR (300 MHz, CDCl3) δ 1.72 (m, 4H), 2.66 (m, 2H), 3.33 (s, 3H), 3.45 (s, 3H), 3.70 (m, 2H), 6.96 (d, 2H), 7.18 (d, 2H), 7.71 (m, 2H), 7.84 (m, 2H). m/z (ESI) 383 [C21H22N2O3S+H]+.
