Hydrochloric Acid → HCID 15439079, compound

Participants

Reaction Steps

To a suspension of sodium amide (1.6 g) in toluene (50 mL) was added a mixture of dithiocarbonic acid O-benzyl ester S-methyl ester (4.0 g) and 4-methoxybenzophenone (3.0 g) at room temperature and the mixture was stirred at room temperature overnight. Hydrochloric acid solution (2 mol/L, 80 mL) was added to the reaction mixture and the mixture was extracted with diethyl ether. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: hexane/dichloromethane=5/1-2/1) to give the title compound (3.4 g).
