Reaction Steps

A solution of 2,4,7-trichloro-quinazoline (35.0 mg, 0.15 mmol, 1.0 equiv) and 1-(3-ethoxy-4-methoxy-benzyl)-piperidin-4-ylamine (47.6 mg, 0.18 mmol, 1.2 equiv; intermediate A1) in DMAc (2 mL) was heated by microwave irradiation to 200° C. for 30 min. Removal of the solvent under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water provided 1.8 mg (3%) of the title compound. MS (ISP): 461.3 [M+H]+.
