A mixture of tert-butyl 3-(2-aminoacetamido)azetidine-1-carboxylate (1.073 g, 4.682 mmol) as prepared in the previous step and commercially available 4-chloro-6-(trifluoromethyl)quinazoline (990 mg, 4.256 mmol) were stirred in anhydrous iPrOH and triethylamine at 90° C. under argon for 1 hour. The reaction mixture was concentrated in vacuo and the residue purified by flash chromatography (silica gel, 0%-5% MeOH/EtOAc) to give a yellow solid after drying under high vacuum.
