2,4-Difluorophenyl isocyanate → N-[(4-Butylphenyl)methyl]-N'-(2,4-difluorophenyl)-N-heptylurea

Participants

Reaction Steps

A solution of 1.55 g of 2,4-diflurophenylisocyanate in hexane was added to a solution of 2.61 g of N-heptyl-4-butylbenzenemethanamine in 15 ml of hexane and the solution was stirred at room temperature for 4 hours, then evaporated. The residual oil was distilled to yield 1-[(4-butylphenyl)methyl]-1-(n-heptyl)-3-[2,4-difluorophenyl]urea as a colorless oil, bp 160°-165° C./120μ.
