HCID 6422Trifluoroacetic acid溶媒

実験手順

A solution of 1.4 g (3.8 mmol) of methyl 2-tert-butylaminosulfonyl-4-[2-(methoxycarbonylamino]ethyl]benzoate in 20 ml of trifluoroacetic acid was stirred for 8 hours at room temperature. The batch was evaporated completely, re-evaporated with toluene, and the residue obtained was crystallized with ethyl acetate/diisopropyl ether. This gave 0.54 g (45%) of methyl 2-aminosulfonyl-4-[2-(methoxycarbonylamino)-ethyl]benzoate of m.p.: 146-149° C.
