Diisopropylethylamine → (R)-tert-butyl 3-((2-chloro-5-fluoropyrimidin-4-ylamino)methyl)-piperidine-1-carboxylate

To a solution of 2,4-dichloro-5-fluoropyrimidine (0.43 g, 2.59 mmol) and (R)-tert-butyl 3-(aminomethyl)piperidine-1-carboxylate (0.56 g, 2.59 mmol) in THF (50 mL) was added iPr2NEt (0.45 mL, 2.59 mmol). The reaction mixture was heated at 80° C. at for 8 h. The solvent was concentrated under reduced pressure and the resulting residue was purified by silica gel chromatography (5-30% EtOAc/hexanes) to afford the desired product, 11a.
