Benzylamine → HCID 67914544, compound

Participants

Reaction Steps

A mixture of 8.0 parts of 3-[2-(diethylamino)ethoxy]-1-[3-(4-fluorophenoxy)propyl]-4-piperidinone, 2.5 parts of benzenemethanamine, 1 part of a solution of thiophene in ethanol 4% and 120 parts of methanol was hydrogenated at normal pressure and at room temperature with 2 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) saturated with ammonia, as eluent. The pure fractions were collected and the eluent was evaporated, yielding 3.6 parts (45%) of cis-3-[2-(diethlamino)ethoxy]-1-[3-(4-fluorophenoxy)-propyl]-4-piperidinamine as a residue (intermediate 126).
