Procedure

Into a 50 mL round-bottom flask, was placed a solution of 1-chloro-7-(trifluoromethyl)phthalazine (prepared as described in the previous step, 1.5 g, 6.47 mmol, 1.00 equiv) in 2-methoxyethyl ether (10 mL), tert-butyl 3-(2-aminoacetamido)azetidine-1-carboxylate (prepared as described in Example 1, Step E) (1.5 g, 6.55 mmol, 1.22 equiv) and triethylamine (1.95 g, 19.31 mmol, 2.99 equiv). The reaction mixture was stirred overnight at 100° C. in an oil bath. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The residue was purified by chromatography over a silica gel column with CH3CN:H2O (3:1). The title compound was obtained as a white solid.
