実験手順

To a stirred solution of N-(2,4-Dimethoxybenzyl)-3-(aminomethyl)pyridin-2-amine (2.04 mmol) and tert-butyl 4-oxopiperidine-1-carboxylate (0.41 g, 2.04 mmol) in DCE (8 ml) and AcOH (115 μL, 2.04 mmol) was added NaBH(OAc)3 (0.43 g, 2.04 mmol) and the reaction stirred at RT until judged complete by LCMS. The reaction mixture was diluted with DCM and sat. aq. Na2CO3, the layers were separated and the organic layer was dried (Na2SO3) and evaporated to dryness. Purification by column chromatography (MeOH/DCM) gave the desired product (0.64 g, 69%). LC/MS (10% to 99%): M/Z (M+H)+ (obs)=457; tR=2.19.
