Participants

Reaction Steps

A mixture of 5-bromo-2-chloro-pyrimidine (1.67 g, 8.63 mmol, 1.0 equiv; commercially available) and 4-amino-piperidine-1-carboxylic acid tert-butyl ester (2.08 g, 10.36 mmol, 1.2 equiv; commercially available) in acetonitrile (10 mL) was heated by microwave irradiation to 120° C. for 40 min. The organic phase was concentrated under reduced pressure and the residue purified by silica column chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of heptane/ethyl acetate providing 1.48 g (48%) of the title compound. MS (ISP): 357.3 [M+H]+.
