Procedure

This compound was prepared according to the procedure C from methyl [2-methyl-4-(4-trifluoromethoxyphenyl)-5,6,7,8-tetrahydro[1]benzothieno[2,3-b]pyridin-3-yl]acetate (0.340 g; 0.78 mmol), LHMDS 1N in THF (1.17 mL; 1.17 mmol), 1-iodopropane (0.152 mL; 1.56 mmol) in DMF (3.9 mL) for 18 h. Purification by flash chromatography on silica gel using a gradient of ethyl acetate (3-40%) in heptane furnished 0.271 g (73%) of the title compound as a yellow oil.
