Participants

Reaction Steps

To a solution of 6-(diphenylmethyl)pyridazin-3(2H)-one (158 mg) in DMF (2 mL) was added NaH (60% in oil, 26 mg) at 5° C. After stirring for an hour at ambient temperature, to the reaction mixture was added a solution of ethyl (3-{3-[(methylsulfonyl)oxy]propoxy}phenoxy)acetate (200 mg) in DMF (0.5 mL), and the resulting mixture was stirred at ambient temperature for 12 hours and then was stirred at 50° C. for 5 hours. After cooling, the reaction mixture was diluted with EtOAc (5 mL) and washed with water (5 mL) and brine (5 mL) two times. The organic layer was dried over anhydrous MgSO4, filtered and evaporated in vacuo to give crude oil. The crude oil was purified by silica gel column chromatography (EtOAc:n-hexane=3:1) to give ethyl (3-{3-[3-(diphenylmethyl)-6-oxopyridazin-1(6H)-yl]propoxy}phenoxy)acetate (230 mg) as a pale yellow oil.
