الإجراء التجريبي

A mixture of 6-chloro-1-[6-(1,4-diazepan-1-yl)-2-pyridyl]pyrazolo[4,3-c]pyridine (0.4094 mmol; 134.6 mg), oxetan-3-one (0.4912 mmol; 35.40 mg), and Molecular sieve (4A) in 1,2-dichloroethane (12 ml) was stirred at room temperature for 4 hours. STAB (0.6141 mmol; 137.0 mg) was added. The reaction was stirred for 3 days. The mixture was filtered through Celite. The filtrate was concentrated and the residue was purified on silica eluted with 0 to 5% MeOH in DCM to afford 6-chloro-1-[6-[4-(oxetan-3-yl)-1,4-diazepan-1-yl]-2-pyridyl]pyrazolo[4,3-c]pyridine (99.2 mg, 63%).
