Reaction Steps

Ethyl 5-(2,2-dimethylpropanoyl)-3-[(4-fluorobenzoyl)amino]-6,6-dimethyl-5,6-dihydropyrrolo[3,4-c]pyrazole-1(4H)-carboxylate (2.0 g, 4.64 mmol) was dissolved in methanol (60 ml), treated with TEA (6.45 ml, 46.4 mmol, 10 eq) and stirred overnight at room temperature. (TLC: CH2Cl2/MeOH 95/5). After evaporation, the solid was treated with diethyl ether/hexane and filtered to afford 1.43 g of the title compound in 86% yield.
