1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 86603617, compound

Participants

Reaction Steps

A mixture of (2E)-3-{6-[(1-benzyl-4-piperidyl)amino]-3-pyridyl}acrylic acid (430 mg), O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (157 mg), HOBt (181 mg) and EDCI (208 mg) in DMF (20 ml) was stirred at ambient temperature for 15 hours. The reaction mixture was poured into a mixture of AcOEt-H2O and the organic layer was washed with brine and dried over MgSO4. The solvent was evaporated in vacuo and the residue was chromatographed on silicagel eluting with AcOEt-MeOH (9:1-8:2). The eluted fractions containing the desired product were collected and evaporated in vacuo to give (2E)-3-{6-[(1-benzyl-4-piperidyl)amino]-3-pyridyl}-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (180 mg).
