Ammonia → 1-(2-methoxyphenyl)-4(1H)-pyridineimine

Participants

Reaction Steps

Ammonia gas was passed into an ice-cooled solution of 3.27 g (10 millimoles) of 1-(2-methoxyphenyl)-4-methoxypyridinium methosulfate in 15 ml of methanol units 2 g of ammonia had been adsorbed. After standing at 25° for 72 hours, the reaction mixture was concentrated, the residue was triturated with cold ethanol and the product was filtered off: 3.01 g (96% yield) of 1-(2-methoxyphenyl)-4(1H)-pyridineimine methosulfate (M.P.=121°-124°) were obtained.
