Reaction Steps

5-Bromo-2-chloro-pyrimidine (18.4 mmol) is added to a solution of (1S,3S,5S)-3-aminomethyl-2-aza-bicyclo[3.1.0]hexane-2-carboxylic acid tert-butyl ester (14.1 mmol) in o-xylene (28 mL). K2CO3 (42.4 mmol) and DIPEA (42.4 mmol) are added and the mixture is heated to 138° C. for 16 h. The mixture is cooled to RT and filtered. The residue is washed with DCM and the combined filtrates are concentrated in vacuo to give a crude product which is purified by flash chromatography (gradient: heptane/EtOAc 90/10 to 85/15). LC-MS: tR=1.05 min; [M+H]+=369.0.
