실험 절차

To a solution of compound 3b (857 mg, 5.5 mmol), in DMF (14 mL) and DCM (25 mL) at room temperature, was added the hydrochloride of 1-amino-2-vinyl-cyclopropanecarboxylic acid ethyl ester, prepared as described in WO03/099274, (1.15 g, 6.0 mmol), HATU (2.29 g, 6.0 mmol) and DIPEA (3.82 mL, 22 mmol). The reaction was stirred under N2-atmosphere at ambient temperature for 1 h. LC/MS analysis showed complete conversion and the reaction mixture was concentrated in vacuo. The residue was redissolved in DCM (100 ml) and 0.1 M HCl (aq) and the phases were separated. The organic phase was washed with NaHCO3 (aq) and brine, dried (MgSO4) and filtered. Removal of the solvent in vacuo afforded the target compound (1.6 g, 99%). LC/MS >95%, m/z (ESI+)=294 (MH+)
