Reaction Steps

27 g of propyl chloroformate were slowly added to a mixture of 41.2 g of m-amino-3-methoxy-crotonanilide, 300 ml of tetrahydrofuran and 22.2 g of triethylamine and the mixture was stirred for 16 hours at 20° C. The mixture was filtered and the filtrate was evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with an 8- 2 methylene chloride-acetone mixture to obtain 40 g of m-(n-propyloxycarbonylamino)-3-methoxy-crotonanilide melting at 115° C. Crystallization from chloroform did not change the melting point.
