Reaction Steps

To a solution of commercially available 2-amino-2-methyl-1-propanol (8.91 g, 100 mmol) in dioxane (20 mL) at 5° C. was added commercially available 3-bromobenzenesulfonyl chloride (2.88 mL, 20 mmol) and the mixture was vigorously stirred at 23° C. for 1 h. Poured into 1 N HCl, diluted with EtOAc, separated phases, washed organic layer with brine, dried over Na2SO4. Removal of the solvent in vacuum left the title compound as a white solid (5.47 g, 89%). MS (ISN) 306.1 [(M−H)−] and 308.2 [(M+2−H)−]; mp 138° C.
