実験手順

To a solution of 10% formic acid in water (50 mL) was added 3-[(2,2,8-trimethyl-4H-[1,3] dioxino [4,5-c]pyridin-5-ylmethyl)-amino]-benzonitrile (1) (336 mg, 0.7 mmol) and the reaction mixture was heated at 100° C. under nitrogen atmosphere. The reaction mixture was then concentrated to dryness. The resulting pale yellow solid was dissolved in small amount of dichloromethane and diethyl ether was added to induce precipitation of a yellow solid. The 4′-[(5-hydroxy-4-hydroxymethyl-6-methyl-pyridin-3-ylmethyl)-amino]-biphenyl-2-sulfonic acid tert-butylamide (2) (215 mg, 70% yield) was collected by filtration as a pale yellow solid.
