Reaction Steps
A 250 mL 3-neck round-bottom flask immersed in an oil bath, equipped with a mechanical stirrer, thermometer, reflux condenser and nitrogen bubbler, was charged with 42.96 g (0.100 mol) of 2-(benzenesulfonyl)-3-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-N-methylacrylamide (II), 100 mL of 2-methoxyethanol and 6.83 g (0.105 mol) of sodium azide. The yellow mixture was heated at 105° C. for 30 h. The cooled orange solution was poured onto a mixture of 150 g of ice and 150 mL of deionized water. The yellow suspension was agitated for 1 h at 5° C. The resulting solid precipitate was filtered off and washed with 5×50 mL of cold deionized water. The recovered solids were dried in vacuo over potassium hydroxide flakes to afford yellow solids, 30.2 g of crude product (I), 98.7% purity by HPLC.
