실험 절차

A mixture of 16 g of N-pentyl-hydroxylamine in 80 ml of isopropyl ether was added to 29.2 g of 3,4-dichlorophenyl isocyanate in 500 ml of isopropyl ether and the mixture was stirred for 16 hours and was evaporated to dryness. The residue was taken up in petroleum ether to obtain 45 g of N-pentyl-N-hydroxy-N'-(3,4-dichlorophenyl)-urea melting at 88° C.
