反応手順

Cyclopentyl-1-cyclopentyl-6-oxo-1,6-dihydropyridazine-3-carboxylate (20 mg, 0.072 mmol) was dissolved in 2 ml THF/water (1/1) and 2 ml NaOH (5M, aq.) was added. The reaction was stirred at 40° C. for 2 h and 5 ml HCl (5M, aq.) was added. The reaction was concentrated and 10 ml of CH2Cl2/MeOH (1/1) was added and the reaction was sonicated for 10 min and filtered. The filtrate was concentrated and used in the next step without further purification. Yield: 11 mg (0.052 mmol, 73%, film, MS m/z: 209(100%, M+1).
