実験手順

A 16.2 g. portion of 2,6-dichloroaniline (Aldrich Chemical Co., Milwaukee, Wis.) was dissolved in 200 ml. 1,2-dichloroethane in a flask under a nitrogen atmosphere at about 25° C. To this was added 25 g. of 2,6-dimethoxybenzoylisocyanate in 25 ml. 1,2-dichloroethane and the solution was warmed to 40° C. for two hours after the addition was complete. Thin layer chromatography on silica gel developed in diethyl ether indicated that no 2,6-dichloroaniline remained. The solvent was removed in vacuo and the residue slurried in methanol. The solids were collected and washed with methanol. Yield 26.5 g. (72%).
