Reaction Steps
A solution of 2.00 g (8.68 mmol) of 6-(2-hydroxyethyl)-4-methyl-2-(2,5-dimethylpyrrol-1-yl)pyridine (from Example 58, Step A) and 1.82 mL (1.32 g, 13.1 mmol) of triethylamine in 20 mL of dichloromethane was cooled to 0° C. and 0.68 mL (1.0 g, 8.8 mmol) of methanesulfonyl chloride was added over 5 min. The mixture was stirred another 25 min at 0° C., diluted with 70 mL of ethyl acetate, and washed with 30 mL each of water, saturated aqueous sodium bicarbonate, and saturated aqueous sodium chloride. The organic layer was dried (sodium sulfate), decanted, and evaporated to give 2.68 g (100% yield) of 6-(2-methanesulfonyloxyethyl)-4-methyl-2-(2,5-dimethylpyrrol-1-yl)pyridine as a viscous pink oil.
