A method for N-acetylation of amines has been developed using acetonitrile as an acylating agent and in situ generated trimethylsilyl iodide as the catalyst under microwave heating condition. The reaction is selective toward aromatic amines while aliphatic amines remain intact. The process eliminates the requirement of toxic acylating reagents like acetic anhydride and acetyl chloride.
Functionalization of quinazolin-4-ones part 1: Synthesis of novel 7-substituted-2-thioxo quinazolin-4-ones from 4-substituted-2-aminobenzoic acids and PPh3(SCN)2

4-(Nitro, amino, acetylamino)-2-aminobenzoic acid were allowed to react with PPh3(SCN)2 and gave the crossholding 7-nitro, 7-acetylamino- and 7-amino-2-thioxo quinazolin-4-ones respectively. The nature of the substituent at position 4 of the 2-aminobenzoic acids has significant influence on the outcome of the cyclisation reaction with PPh 3(SCN)2. Similarly, the nature of the substituent at position 7 of the 2-substituted quinazolin-4-ones significantly affected the ease with which alkylation reactions could be performed. The alkylation selectivity of the 7- substiuted-2-thioxo quinazolin-4-ones was found to depend on the nature of the alkyl halide and the nature of the substituent at position 2.
