Participants

Reaction Steps

Following general procedure E: a solution of 4,6-dimethyl-pyrimidine-5-carboxylic acid (3-{4-[(thiophen-3-ylmethyl)-amino]-piperidin-1-yl}-butyl)-amide (41 mg, 0.1 mmol), 4-carboxymethyl-piperidine-1-carboxylic acid tert-butyl ester (50 mg, 0.22 mmol), EDCI (39 mg, 0.20 mmol), HOBT (27 mg, 0.20 mmol), and DIPEA (0.05 ml, 0.3 mmol) in CH2Cl2 (2 ml) was stirred overnight. Purification of the crude product by column chromatography on silica gel (CH2Cl2/MeOH, 9:1) afforded 4-{[(1-{3-[(4,6-dimethyl-pyrimidine-5-carbonyl)-amino]-1-methyl-propyl}-piperidin-4-yl)-thiophen-3-ylmethyl-carbamoyl]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (50 mg, 80%).
