Methanol → 9-[(4-fluorophenyl)methyl]-6-methoxy-8-[[1-(phenylmethyl)-4-piperidinyl]methyl]-9H-purine

Participants

Reaction Steps

To a previously prepared sodium methoxide solution, starting from 25 parts of sodium in 400 parts of methanol, were added 49.4 parts of 6-chloro-9-[(4-fluorophenyl)methyl]-8-[[1-(phenylmethyl)-4-piperidinyl]methyl]-9H-purine. After stirring for 8 hours at reflux temperature, the reaction mixture was cooled and 1000 parts of water were added. The precipitated product was filtered off and dried, yielding 34.5 parts (70.4%) of 9-[(4-fluorophenyl)methyl]-6-methoxy-8-[[1-(phenylmethyl)-4-piperidinyl]methyl]-9H-purine (compound 184).
