2-Chloro-4,6-dimethylpyrimidine → HCID 67342807, compound

Participants

Reaction Steps

A mixture of 2-chloro-4,6-dimethyl-pyrimidine (1.50 g, 10.52 mmol, 1.0 equiv; commercially available), 4-amino-piperidine-1-carboxylic acid tert-butyl ester (2.53 g, 12.62 mmol, 1.2 equiv; commercially available) and N-ethyl diisopropylamine (2.15 mL, 1.63 g, 12.62 mmol, 1.2 equiv) in acetonitrile (8 mL) and DMAc (2 mL) was heated by microwave irradiation to 160° C. for 1 h and then to 180° C. for 30 min. The reaction mixture was concentrated under reduced pressure and the crude material purified by silica column chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of heptane/ethyl acetate providing 1.47 g (46%) of the title compound. MS (ISP): 307.5 [M+H]+.
