Procedure

To a solution of 55 mg (0.254 mmol) 6-phenyl-octahydro-indolizin-6-ylamine (example A.3) and 130 ul (0.762 mmol) N-ethyldiisopropylamine in dichloromethane (0.9 ml) was added drop-wise a solution of 63 mg (0.22 mmol) 2-methoxy-6-methylsulfanyl-4-trifluoromethyl-benzoyl chloride (example B.1) in dichloromethane (0.6 ml) at room temperature. The mixture was stirred at room temperature for 1 hour. The solution was washed once with a 2M sodium carbonate solution. The aqueous layer was extracted once with dichloromethane. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified with flash column chromatography on silica eluting from n-heptane and ethyl acetate (0 to 50%) to provide 26 mg (y: 22%) of example 3 (2-methoxy-6-methylsulfanyl-N-(6-phenyl-octahydro-indolizin-6-yl)-4-trifluoromethyl-benzamide, diastereoisomer 1, first running compound) as a light yellow gum, MS (m/e): 465.2 (M+H+) and 49 mg (y: 41.5%) of example 4 (2-methoxy-6-methylsulfanyl-N-(6-phenyl-octahydro-indolizin-6-yl)-4-trifluoromethyl-benzamide, diastereoisomer 2, second running compound) as a white solid, MS (m/e): 465.2 (M+H+).
