Procedure
4-Methylsulfonyl-2-aminophenol (Intermediate 102) (690 mg, 3.68 mmol) was dissolved in chloroform (30 mL) and saturated sodium bicarbonate (20 mL). The biphasic reaction mixture was cooled to 0° C. and bromoacetyl bromide (889 mg, 4.42 mmol) was added dropwise. The reaction was stirred overnight at room temperature. The layers were separated and the aqueous layer was filtered to yield the desired product as a solid, 280 mg (33%).
