Reaction Steps
A mixture of the quaternary salt of Procedure 94 and 10% palladium on carbon in abs. EtOH is subjected to hydrogenolysis at a pressure of about 50 psig. The spent catalyst is removed by filtration, the filtrate concentrated in vacuo, and the residue dissolved in water. Treatment with concentrated NH4OH liberates the free base which is collected and dried.
