Reaction Steps
A suspension of potassium 8-iodo-1-methyl-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxylate (394 mg, 1.0 mmol) in anhydrous dimethylformamide (10 mL) was treated with N-ethyl-N′,N′-diisopropyl carbodiimide hydrochloride (EDCI) (287 mg, 1.5 mmol) and with ammonium 1H-1,2,3-benzotriazol-1-ate (304 mg, 2 mmol). The reaction was stirred at room temperature overnight. The reaction was diluted with water and the resulting precipitate was collected by filtration to afford the title compound (320 mg, 90% yield).
