Reaction Steps

A solution of 2-(6-chloro-pyridin-3-yl)-1H-benzoimidazole (23.0 mg, 0.10 mmol, 1.0 equiv; commercially available) and 1-(3-ethoxy-4-methoxy-benzyl)-piperidin-4-ylamine (39.7 mg, 0.15 mmol, 1.5 equiv; intermediate A1) in ethylene glycol (2 mL) was heated by microwave irradiation to 220° C. for 20 min. Removal of the solvent under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water provided 4.0 mg (9%) of the title compound. MS (ISP): 456.6 [M−H]−.
