Procedure
A mixture of N-(2-tert-butylphenyl)acetamide (Reference Example 17, 5.93 g, 31.0 mmol) and sulfuryl chloride (10.5 g, 77.5 mmol) in acetic acid (190 mL) was stirred at 50° C. for 16 h. The reaction mixture was partitioned between ethyl acetate and water, and the organic layer was washed with 10% aqueous NaHCO3, and saturated brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting solid was recrystallized from toluene/diethyl ether to give the title compound (3.73 g) as a white solid. The mother liquid was concentrated under reduced pressure and the residue was purified by flash column chromatography (silica gel, 4:1-1:4 hexane/ethyl acetate) to provide the title compound (1.05 g) as a white solid.
