Reaction Steps
Sodium hydroxide (0.5 ml of 2M in water) was added to a solution of ethyl 3-(phenylsulfanyl)-6-(3-pyridylmethoxy)benzo[b]thiophene-2-carboxylate (Example 1, 190 mg, 0.45 mmol) in 1,4-dioxane, and the mixture heated to 60° C. for 4 hours. The solvents were removed under reduced pressure, and the residue was dissolved in water (15 ml) and washed with ethyl acetate (25 ml). The aqueous layer was separated and acidified by dropwise addition of acetic acid until a white solid precipitated. The solid was isolated by filtration and dried under vacuo to give the title compound as a colourless solid (140 mg).
