Reaction Steps

In 30 ml of toluene, 0.8 g (5.7×10−3 moles) of 6-chloropyridine-3-aldehyde and 10 g of Na2SO4 were mixed and while the mixtures was stirred, a 40% aqueous solution of methylamine (1.4 g, 1.1×10−2 mole) was added dropwise over 30 minutes, followed by addition of 10 g of MgSO4. The mixture was allowed to stand at room temperature overnight, after which it was filtered. The filtrate was concentrated to give 0.6 g (yield 68%) of N-(6-chloro-3-pyridylmethylidene)methylamine as crystals.
