実験手順

A mixture of 2-chloro-6,7-dimethoxy-4-piperidin-1-yl-quinazoline (3.08 g, 10.00 mmol, 1.0 equiv; commercially available from Specs Research Laboratory, The Netherlands), 4-amino-piperidine-1-carboxylic acid tert-butyl ester (2.00 g, 10.00 mmol, 1.0 equiv; commercially available), rac-2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (0.25 g, 0.40 mmol, 0.04 equiv), tris(dibenzylideneacetone)dipalladium(0) (0.21 g, 0.20 mmol, 0.02 equiv) and KOtert-Bu (1.35 g, 12.01 mmol, 1.2 equiv) in toluene (10 mL) was heated under Ar by microwave irradiation to 120° C. for 2 h. The crude reaction mixture was filtered through Hyflo Super Cel, a sat. solution of sodium chloride (100 mL) was added and the mixture extracted with ethyl acetate (3×50 mL). The combined organic phases were concentrated by evaporation under reduced pressure and the residue purified on a Isolute flash NH2 chromatography column using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of heptane/ethyl acetate providing 1.90 g (40%) of the title compound. MS (ISP): 472.4 [M+H]+.
