4-Chlorophenyl Isocyanate → HCID 86612126, compound

Participants

Reaction Steps

To a solution of methyl mandelate (0.83 g) and triethylamine (0.51 g) in THF (40 ml) was added 4-chlorophenyl isocyanate (0.77 g). The reaction mixture was mixed at 60° C. for 3 hours, and then the reaction solution was concentrated under reduced pressure. The residue was dissolved in ethyl acetate, washed with water and saturated brine and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified with silica gel column (ethyl acetate/hexane=1/6 to 1/3) to obtain the title compound as a pale brown crystal (1.5 g, 91%).
