Phenyl isocyanate → N-{6-Oxo-7-[(triphenylmethyl)sulfanyl]heptyl}-N'-phenylurea

Participants

Reaction Steps

To a solution of 7-amino-1-tritylsulfanyl-heptan-2-one (0.36 g, 0.86 mmol) in dichloromethane (10 mL) was added phenylisocyanate (0.10 ml, 0.92 mmol). The mixture was stirred at room temperature for 2 h. Solvent was then removed in vacuo and the crude product was purified by column chromatography (dichloromethane/MeOH=100/1 to 40/1) to provide 1-(6-Oxo-7-tritylsulfanyl-heptyl)-3-phenyl-urea (0.43 g, 93%).
