Reaction Conditions

Reaction Steps

Dimethyl sulfoxide (60 μL, 0.85 mmol) is added at −78° C. to a solution of oxalyl chloride (36 μL, 0.41 mmol) in dichloromethane (2 mL). After stirring at −78° C. for 10 minutes, a solution of [6-(2,6-diethyl-phenyl)-4-methoxy-2-methyl-pyridin-3-yl]-(1,2,3,4-tetrahydro-naphthalen-1-yl)-methanol (138 mg) in dichloromethane (2 mL) is added and the mixture is stirred for 40 minutes more. Triethylamine (0.24 mL, 1.7 mmol) is then added. After 10 minutes, the mixture is allowed to warm to room temperature and quenched with water. Extraction with dichloromethane, drying (Na2SO4), and concentration followed by flash chromatography provides [6-(2,6-diethylphenyl)-4-methoxy-2-methylpyridin-3-yl]-(1,2,3,4-tetrahydronaphthalene-1-yl)methanone. 1H NMR (CDCl3) 7.30 (dd, 1H), 7.16-7.12 (m, 4H), 7.0 (t, 1H), 6.9 (d, 1H), 6.6 (s, 1H), 4.4 (s, 1H), 3.8 (s, 3H), 2.90-2.76 (m, 2H), 2.43-2.33 (m, 4H), 2.3 (s, 3H), 2.03-1.84 (m, 4H), 1.15-1.04 (m, 6H).
