Reaction Steps

(1aR,5aR)-2-(6-Chloro-pyrazin-2-yl)-1a,2,5,5a-tetrahydro-1H-2,3-diaza-cyclopropa[a]pentalene-4-carboxylic acid (2-hydroxy-1,1-dimethyl-ethyl)-amide (25 mg, 0.072 mmol) was added to a 3.7 M methanol solution of sodium methoxide (0.583 mL, 2.156 mmol). The white suspension was stirred at 23° C., for 30 min. 1 M HCl (2.5 mL) and water (5 mL) were added. The mixture was extracted with dichloromethane (3×5 mL). The combined organic extracts were concentrated under reduced pressure and purified by silica gel flash chromatography to provide the title compound (12 mg) as a white solid. LCMS m/z=344.3 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 0.47 (td, J=4.7, 3.3 Hz, 1H), 1.25 (td, J=7.9, 4.8 Hz, 1H), 1.419 (s, 3H), 1.422 (s, 3H), 2.26-2.32 (m, 1H), 2.71-2.76 (m, 1H), 2.92 (d, J=16.9 Hz, 1H), 3.02 (dd, J=16.6, 6.2 Hz, 1H), 3.71 (s, 2H), 4.03 (s, 3H), 4.70 (bs, 1H), 6.96 (s, 1H), 8.17 (d, J=0.5 Hz, 1H), 8.75 (d, J=0.5 Hz, 1H).
