| abstract | PURPOSE: To obtain the title compound useful as aralgesics and intermediates for medicines in a very short step in high yield, by treating a pypridinium salt with a base to give a specific compound, which is hydrolyzed under acidic conditions. n CONSTITUTION: A pyridinium salt of formula I: [R 1 is lower alkyl or aralkyl group; R 2 ' is H when X' is 0, R 2 ' is lower alkyl or aryl group when Z' is imino group; R 3 is H or lower alkyl group; -W=Y-Z' is formula II (R 4 is H, lower alkenyl group. etc.) etc.; X is halogen] is treated with a base, e.g. sodium hydroxide or sodium carbonate, to give a compound of formula III: (A is R 1 -N=CH; R 2 is present when Z is N, and the same as R 2 '; -W=Y-Z is formula IV, etc.), which is hydrolyzed under acidic conditions with hydrochloric acid to form the compound of formula V: (B is R 1 -N=CH, etc.). n COPYRIGHT: (C)1979,JPO&Japio |
