Participants

Reaction Steps

A mixture of 220 mg (1.1 mmol) 3-aminomethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (commercially available), 188 mg (1 mmol) 2,6-dichloro-benzooxazole (commercially available) and 303 mg (3 mmol) NEt3 in 4 mL DCM was stirred at room temperature over night. After evaporation to dryness the residue was purified with flash column chromatography on silica eluting with a gradient formed from ethyl acetate and heptane.
