Phenyl isocyanate → HCID 13201298, compound

Participants

Reaction Steps

6.1 g (0.05 mol) of phenyl isocyanate were added dropwise to a solution of 9.65 g (0.05 mol) of N-4-fluorobenzyl-N-cyclopentylamine in 80 ml of anhydrous methylene chloride, while cooling with ice and stirring. The mixture was stirred for 30 minutes at room temperature and for 30 minutes at 40° C., the solvent was stripped off in vacuo, and the residue was recrystallized from acetonitrile. 14.1 g of N-4-fluorobenzyl-N-cyclopentyl-N'-phenylurea of melting point 120° to 121° C. were obtained.
