Procedure

To a solution of (1aR,5aR)-2-(4-cyano-pyridin-2-yl)-1a,2,5,5a-tetrahydro-1H-2,3-diaza-cyclopropa[a]pentalene-4-carboxylic acid (50 mg, 0.188 mmol), (S)-2-amino-4,4,4-trifluorobutan-1-ol hydrochloride (33.7 mg, 0.188 mmol), and triethylamine (0.052 mL, 0.376 mmol) in DMF (2 mL) was added HATU (71.4 mg, 0.188 mmol). The mixture was stirred at 23° C. for 30 min and purified by HPLC followed by preparative TLC to give the title product (6 mg) as a white solid. LCMS m/z=392.4 [M+H]+; 1H NMR (400 MHz, CDCl3) δ 0.45 (td, J=4.7, 3.3 Hz, 1H), 1.24-1.29 (m, 2H), 2.26-2.32 (m, 1H), 2.54-2.69 (m, 2H), 2.77-2.82 (m, 1H), 2.91 (d, J=16.7 Hz, 1H), 3.01 (dd, J=16.7, 6.4 Hz, 1H), 3.87 (d, J=4.0 Hz, 2H), 4.34-4.42 (m, 1H), 7.24 (d, J=8.1 Hz, 1H), 7.41 (dd, J=5.1, 1.1 Hz, 1H), 8.17 (s, 1H), 8.62 (d, J=5.1 Hz, 1H).
