Reaction Steps

A mixture of 500 mg of 6C, 5 ml of 2-propenamine and 25 ml of ethanol was refluxed for 18 hours. The sovlent was then stripped off and the residue was taken up in methylene chloride, triturated with hexane and cooled to give a solid. The solid was redissolved in ethanol, the solution was passed through a short silica gel column and the eluent was stripped of solvent. The residue was recrystallized from methylene chloride/hexane to give 6, as white needles, mp: 171°-171.5° C.
