A one pot selective mend N-alkylation of primary amides, thioamides, carbamates and ureas has been developed using aromatic and aliphatic aldehydes as alkylating agents and trifluoroacetic acid / triethylsilane as reagents. Application to an efficient synthesis of a primary amine from the correspond
## Abstract By condensing the potassium salt of isatinic acid ‐ (__o__‐aminophenyl)‐glyoxylic acid ‐ with urea, __N__‐substituted ureas and ethyl carbamate, 2‐hydroxyquinazoline‐4‐carboxylic acid was obtained, in excellent yield. In a similar condensation with guanidine, potassium isatinate reacted
Ureas were synthesized from methyl carbamates which were obtained by reaction of amines with dimethylcarbonate. Both reactions were catalyzed by g-Al 2 O 3 .
