Reaction Steps

To 750 ml. of methanol and 80.0 g. (0.22 mole) of 4-(1-phenylethylaminomethyl)-4,5-dihydro-3,3-diphenylfuran-2(3H)one was added 3.0 g. of palladium hydroxide catalyst and the mixture was shaken in three atmospheres of hydrogen at 70° C. for 18 hrs. Upon filtering starting material was found to be present; fresh catalyst was added to the solution which was shaken in three atmospheres of hydrogen at 70° C. for three more hours. After filtering the filtrate was concentrated in vacuo. The residue was dissolved in 100 ml. of ethyl acetate, and 100 ml. of isopropyl ether was added. A portion of the crystallized material was recrystallized from the same solvent system to give product melting at 145°-148° C.
