Reaction Steps
Using General Procedure B: Reaction of 4-[(5-Chloro-3-methyl-pyridin-2-ylmethyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester and 3-Isopropyl-pyridine-2-carbaldehyde with NaBH(OAc)3 in CH2Cl2 gave 4-[(5-Chloro-3-methyl-pyridin-2-ylmethyl)-(3-isopropyl-pyridin-2-ylmethyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester as a white solid. Deprotection with TFA using General Procedure F gave (5-Chloro-3-methyl-pyridin-2-ylmethyl)-(3-isopropyl-pyridin-2-ylmethyl)-piperidin-4-yl-amine as a colorless oil.
