HCID 222931603-(Aminomethyl)-N-(2,4-dimethoxybenzyl)pyridin-2-amine

Procedure

A solution of 2-(2,4-Dimethoxybenzylamino)pyridine-3-carbonitrile (0.55 g, 2.04 mmol) and LiAlH4 (2.2 ml of 1N, 4.4 mmol) was stirred at RT until the reaction was judged complete by LCMS. The reaction was quenched with sat. aq. Na2CO3 and the layers were separated. The organic layer was dried (Na2SO4) and the solvents removed under reduced pressure giving the desired product which was used without further purification. LC/MS (10% to 99%): M/Z (M+H)+ (obs)=274; tR=0.28.
