Reaction Steps

A mixture of 16.6 g of 40% aqueous MeNH2 solution and 52 ml of CH3CN was cooled with ice and 6.08 g (0.043 mole in terms of pure product) of crude (6-methyl-3-pyridyl)methyl chloride was added dropwise with constant stirring. After completion of dropwise addition, the mixture was stirred at room temperature for 1.5 hours, at the end of which time the solvent was distilled off. The solid residue was extracted with CH2Cl2 and the CH2Cl2 layer was dried over MgSO4. The CH2Cl2 was distilled off and the residue was diluted with 70 ml of Et2O and filtered to remove the insoluble matter. Finally the filtrate was concentrated to recover 4.60 g of the title compound as a crude oil.
