実験手順
To a solution of methyl [2-methyl-4-phenyl-6,7-dihydro-5H-cyclopenta[4,5]thieno[2,3-b]pyridin-3yl]acetate (0.061 g; 0.181 mmol) in dioxane (4 mL) and water (1 mL) was added a 1N lithium oxide solution (1 mL; 1 mmol). The reaction mixture was heated at 65° C. for 2.5 h. After cooling to room temperature, the reaction mixture was acidified with 1N HCl (pH˜2) and partially concentrated under reduced pressure. The residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over sodium sulphatesulphate, filtered and concentrated under reduced pressure. The residue was crystallized from a mixture of ethyl acetate/heptane to afford 0.031 g (54%) of the title compound as a beige powder.
