Reaction Steps

The mixture of 10 g of 5-(m-chlorobenzylamino)-pyridine-2-carboxylic acid methyl ester, 13 ml of 35% aqueous formaldehyde and 13 ml of formic acid is stirred at the steam bath for one day. It is evaporated, the residue boiled with 100 ml of methanol, until dissolution, the solution filtered hot and the filtrate cooled. The precipitate formed is collected and recrystallized from methanol, to yield the 5-(N-methyl-N-m-chlorobenzylamino)-pyridine-2-carboxylic acid melting at 138°-140°.
