6-Chloro-3-pyridinecarbonitrile → 6-[1-(3-Ethoxy-4-methoxy-benzyl)-piperidin-4-ylamino]-nicotinonitrile

Participants

Reaction Steps

A solution of 6-chloro-nicotinonitrile (20.8 mg, 0.15 mmol, 1.0 equiv; commercially available) and 1-(3-ethoxy-4-methoxy-benzyl)-piperidin-4-ylamine (47.6 mg, 0.18 mmol, 1.2 equiv; intermediate A1) in DMAc (1.5 mL) was heated by microwave irradiation to 180° C. for 10 min. Removal of the solvent under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water provided 2.2 mg (4%) of the title compound. MS (ISP): 367.3 [M+H]+.
