• Bromination of 1a in a heterogeneous mixture of dichloromethane, aqueous sodium hydrogen carbonate and methanol gave methyl N-tosyl-methylcarbamate (3a) in a yield of 90% (compare ref. 1). Carbamoylchloride 2a was characterized chemically by conversion with ethanol into ethyl N-tosylmethylcarbamate (3b)
