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-3-methylbutan-1-ol (19.37 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 to give the title compound (53 mg) as a white solid. LCMS m/z=352.3 [M+H]+; 1H NMR (400 MHz, CDCl3) δ 0.46 (td, J=4.7, 3.3 Hz, 1H), 1.04 (d, J=6.8 Hz, 3H), 1.05 (d, J=6.7 Hz, 3H), 1.26 (td, J=8.0, 4.9 Hz, 1H), 2.05 (oct, J=6.8 Hz, 1H), 2.26-2.32 (m, 1H), 2.52 (t, J=5.6 Hz, 1H), 2.78-2.82 (m, 1H), 2.93 (d, J=16.8 Hz, 1H), 3.02 (dd, J=16.7, 6.4 Hz, 1H), 3.75-3.92 (m, 3H), 7.00 (d, J=7.8 Hz, 1H), 7.41 (dd, J=5.1, 1.4 Hz, 1H), 8.17 (s, 1H), 8.62 (d, J=5.1 Hz, 1H).
