YieldReaction ConditionsOperation in experiment
42% To a solution of 2-amino-5-bromopyridine-3-sulfonyl chloride (reagent preparation 25, step 1) (0.40 g, (1.47 mmol) in a mixture of 1 ,4-dioxane (8.0 mL) and water (1.0 mL) was added triphenylphosphine (1.64 g, 6.25 mmol) and the reaction mixture was stirred for 50 minutes at room temperature. Potassium carbonate (0.35 g, 2.50 mmol) was introduced, followed by <strong>[35979-69-2]4-bromo-2-methyl-2-butanol</strong> (Tetrahedron Letters 2000, 41(38), 7337-7340) (0.31 g, 1.86 mmol) and the reaction mixture was stirred at 80 C for 16 hours. After cooling to room temperature the reaction mixture was concentrated and the residue was partitioned between brine (50 mL) and ethyl acetate (100 mL). The organic layer was separated and washed with brine (50 mL), dried over sodium sulfate, filtered and concentrated. Gradient flash chromatography (25% to 50% ethyl acetate in hexane) provided 4-[(2-amino-5-bromopyridin-3-yl)thio]-2-methylbutan-2-ol (0.18 g, 42%); MS (EI) for C10H15BrN2OS: 292 (MH+).
