Procedure

To a solution of methyl [2-methyl-4-(pyridin-3-yl)-5,6,7,8-tetrahydro[1]benzothieno[2,3-b]pyridin-3-yl]pentanoate (0.058 g; 0.147 mmol) in methanol (1.5 mL) was added a solution of sodium hydroxide 5 N (0.29 mL) and the mixture was heated at 60° C. for 18 h. After cooling, the reaction mixture was concentrated under reduced pressure. The residue was dissolved in ethyl acetate and the mixture was acidified with HCl (1N) until pH 1. The organic layer was washed with brine, water, dried over magnesium sulphate and concentrated under reduced pressure to furnish 0.023 g (42%) of the title compound as a white solid.
