Procedure

A solution of 50.5 g. of 4-(allylamino)hydrocinnamic acid and 34.4 ml. of boron trifluoride etherate in 200 ml. of methanol is stirred under reflux for 44 hours, allowed to cool, and poured into 1.20 liters of ice-cold 5% aqueous sodium carbonate solution. The white solid is collected by filtration and recrystallized from benzeneethanol to yield methyl 4-(allylamino)hydrocinnamate.
