Benzyl chloroformate → HCID 13838839, compound

Participants

Reaction Steps

4-Cyclohexene-1,2-diamine hydrochloride (4.0 g) was dissolved in a solvent mixture of water (20 mL) and acetonitrile (20 mL), and to the solution were added benzyl chloroformate (7.66 mL) and potassium carbonate (14.9 g), followed by stirring at room temperature for 3 days. The reaction mixture was poured into water, and the thus-obtained mixture was extracted with methylene chloride. The organic layer was washed with saturated brine, and was dried over sodium sulfate anhydrate. The solvent was distilled away under reduced pressure, and the residue was purified by silica gel column chromatography (methylene chloride), to thereby give the title compound (8.22 g).
