Reaction Steps

0.24 g of 55% sodium hydride dispersion in mineral oil were added to a solution of 1.63 g of N-(2,6-dichlorobenzoyl)-N'-(4-hydroxyphenyl)urea in 15 ml of dimethylformamide; the reaction mixture was stirred for 20 minutes with external cooling with water until a bright solution was obtained. 1.6 ml of 77% 1-phenylheptylbromide were added to this solution after which the reaction mixture was left to stand at room temperature for approximately 2 days. After pouring the reaction mixture on a mixture of ice water and petroleum ether a crystalline product was obtained which was sucked off, washed with successively water and little isopropanol and dried in air. The desired product was obtained in a yield of 0.87 g; melting point 146°-149° C. The product was identified by means of its NMR spectrum. The following compounds were prepared in a corresponding manner:
