Reaction Steps
To a suspension of potassium hydride (0.18 g, dry weight, 4.5 mmol; obtained from washing 0.52 g of 35% potassium hydride dispersion in mineral oil with hexanes and drying under a stream of argon) in anhydrous THF (25 mL), N-tert-butoxycarbonyl-4-(3-tolylsulfanyl)-4-hydroxymethylpiperidine (0.96 g, 2.8 mmol; Example 106, Step B) in THF (5 mL) was added. The resultant mixture was stirred at room temp. for 1 h., and treated with methyl iodide (0.31 mL, 4.97 mmol). The reacting mixture was stirred at room temp. overnight. The product mixture was cooled to 0° C., quenched with water, and diluted with ethyl acetate. The organic extract was washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under vacuum to provide the title compound.
