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 2.0 M THF solution of dimethylamine (0.719 mL, 1.438 mmol). The reaction was heated under microwave irradiation for 30 min at 100° C., then for 60 min at 110° C. The mixture was concentrated and purified by silica gel flash chromatography to provide the title compound (18 mg) as a white solid.
