Procedure: (MS(m/e): 449.1 (MH+)), were prepared from 2-bromo-N-methyl-2-phenyl-acetamide (commercially available) and 4-[2-(4-methoxy-phenyl)-ethyl]-2,3-dimethyl-4,5,6,7-tetrahydro-thieno [3,2-c]pyridine both as light brown solid.

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 615 mg (2.29 mmol) 5-[2-(4-methoxy-phenyl)-ethyl]-5,6,7,8-tetrahydro-[1,6]naphthyridine in 25 mL acetonitrile, were added 682 mg (2.98 mmol) 2-bromo-N-methyl -2-phenyl-acetamide, 1.2 mL (6.87 mmol) N-ethyldiisopropylamine and 343 mg (2.29 mmol) sodium iodide. The solution was stirred at 60° C. for 6 h. The solvent was removed in vacuo and the residue was taken in ethyl acetate. The mixture was washed once with water and once with a 2M Na2CO3 solution, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified on silica eluting with a gradient formed from heptane and ethyl acetate. The product containing fractions were evaporated to yield 330 mg (35%) of 2-{5-[2-(4-methoxy-phenyl)-ethyl]-7,8-dihydro-5H-[1,6]naphthyridin-6-yl}-N-methyl-2-phenyl-acetamide (diastereoisomer 1, first eluting diastereoisomer) as yellow foam The solvent was removed in vacuo The mixture was washed once with water and once with a 2M Na2CO3 solution dried over Na2SO4 filtered concentrated in vacuo The residue was purified on silica eluting with a gradient formed from heptane and ethyl acetate The product containing fractions were evaporated

Procedure: To a solution of 300 mg (0.92 mmol) 2-methyl-4-[2-(4-trifluoromethyl-phenyl)-ethyl]-4,5,6,7-tetrahydro-thieno[3,2-c]pyridine in 13 mL acetonitrile was added 210.3 mg (0.92 mmol) 2-Bromo-N-methyl-2-phenyl-acetamide (commercially available), 473 uL (2.76 mmol) N-ethyldiisopropylamine and 138 mg (0.92 mmol) sodium iodide. The solution was stirred for 18 h at 60° C. The solvent was removed in vacuo and the residue was dissolved in ethyl acetate and washed with water and Na2CO3 aq. The organic layer was dried over Na2SO4, filtered and evaporated. The residue was purified on silica eluting with a gradient formed from heptane and ethyl acetate. The diastereoisomeric product eluting first (obtained after evaporation from the product containing fractions) was dissolved in methanol, treated with Norit, heated to reflux, filtered and evaporated to dryness to yield 46 mg (11%) of N-methyl-2-{2-methyl-4-[2-(4-trifluoromethyl-phenyl)-ethyl]-6,7-dihydro-4H-thieno[3,2-c]pyridin-5-yl}-2-phenyl-acetamide (diastereoisomer 1) (MS(m/e): 472.9 (MH+)) as light yellow oil.
