Reaction Steps

12 g of n-butyl chloroformate were slowly added to a mixture of 16.5 g of m-amino-3-methoxy-crotonanilide, 320 ml of tetrahydrofuran and 8.9 g of triethylamine cooled to 5° C. and the mixture was stirred for 16 hours and then vacuum filtered. The residue was chromatographed over silica gel and was eluted with an 8- 2 methylene chloride-acetone mixture to obtain 22 g of m-(n-butoxycarbonylamino)-3-methoxy-crotonanilide melting at 100° C.
