Process for the preparation of aryl esters of N-alkyl carbamic acids
Aryl esters of N-alkyl carbamic acids are prepared by reacting an alkyl N-alkyl carbamate of the general formula R1 - NH - COO - R3 wherein R1 and R3 are both alkyl groups with a substituted phenol in the presence of a halogen-containing phosphorus compound to produce the desired ester of the formula R1 -NH - COOR2 wherein R1 is an alkyl group and R2 is an aryl group.
