반응 단계
A solution of Methyl-6-difluoromethyloxybenzo[4,5]furo[3,2-c]pyridine-9-carboxylate (6.5 g, 0.0221 moles), sodium hydroxide (4.0 g, 0.110 moles) and water (10.0 mL) in methanol (60.0 mL) was refluxed for 1-1.5 hrs. Methanol was removed under reduced pressure. The residue obtained was diluted with water (50.0 mL) and acidified with acetic acid. The solid separated was filtered, washed with water (2×100 mL) and dried to get 5.5 g of product as off-white solid.
