Participants

Reaction Steps

Triethylsilane (1.0 ml) was added to a stirred solution of 2-[1-hydroxy-1-phenylmethyl]-5-methyl-7-(2-methylpropyl)thieno[2,3-d]pyridazin-4(5H)-one (example 14, 1.44 g) in trifluoroacetic acid (2 ml) and dichloromethane (10 ml) at room temperature. After 24 hours, saturated sodium hydrogen carbonate solution (100 ml) was added and the mixture was extracted with ethyl acetate (100 ml). The organic extracts were washed twice with saturated sodium hydrogen carbonate solution, then with brine, and then dried, filtered and evaporated. The residue was purified by column chromatography, eluting with ethyl acetate:isohexane (1:4 then 1:3), to give the title compound (1.11 g) as a solid.
