To a solution of (1aS,5aS)-2-(4-chloro-pyridin-2-yl)-1a,2,5,5a-tetrahydro-1H-2,3-diaza-cyclopropa[a]pentalene-4-carboxylic acid (100 mg, 0.363 mmol), methyl 2-amino-3-fluoro-2-(fluoromethyl)propanoate hydrochloride (76 mg, 0.399 mmol) and triethylamine (0.101 mL, 0.725 mmol) in DMF (2 mL) was added HATU (138 mg, 0.363 mmol). The reaction was stirred at 50° C. for 2 h, then concentrated. The residue was purified by silica gel flash chromatography to give the title compound as a white solid. LCMS m/z=411.2 [M+H]+; 1H NMR (400 MHz, CDCl3) δ 0.46 (td, J=4.7, 3.3 Hz, 1H), 1.25 (td, J=7.8, 4.7 Hz, 1H), 2.24-2.30 (m, 1H), 2.79-2.84 (m, 1H), 2.89 (d, J=16.8 Hz, 1H), 2.99 (dd, J=16.4, 6.2 Hz, 1H), 3.89 (s, 3H), 4.81-5.12 (m, 4H), 7.22 (dd, J=5.3, 1.8 Hz, 1H), 7.51 (s, 1H), 7.98 (d, J=1.8 Hz, 1H), 8.36 (d, J=5.3 Hz, 1H).
