YieldReaction ConditionsOperation in experiment
75% With 1-methyl-1H-imidazole; In dichloromethane; at -10 - -5℃; for 0.5h;Inert atmosphere; <strong>[1421840-44-9](R)-<strong>[1421840-44-9]N-(1-(5-chloro-2-hydroxyphenyl)ethyl)-4-methylbenzenesulfonamide</strong></strong> (1,100.0g, 307.69mmol) in anhydrous dichloromethane (1200ml) solution of -10 until cooled, then phenyl phosphonic acid dichloride (57.55ml, 369.23mmol, 90% by weight) is added to the reaction mixture. Then, while maintaining the reaction temperature under an argon atmosphere at less than -5 C., is added 1-methylimidazole (61.02ml, 769.2mmol) over 30 minutes. After completion of the reaction, the reaction is quenched water (500mL) was added to the reaction mixture. The phases were separated and the organic phase was washed with 1 N HCl 400 ml, then water 100 ml, then washed with saturated sodium bicarbonate solution 200 ml. Then, the organic phase was filtered through Celite, and then concentrated. The residue, EtOAc: hexane (500ml: 1200ml) was recrystallized to give the 2a (103g, 75%) as a white solid

YieldReaction ConditionsOperation in experiment
78% With dmap; In dichloromethane; at -10 - 0℃; for 2.5h;Inert atmosphere; (R)-N-(1-(5- chloro-2-hydroxyphenyl)ethyl)-4-methylbenzenesulfonamide (1,100.0g, 307.69mmol) in anhydrous dichloromethane (800ml) solution of -10 until cooled, then add methylphosphonic acid dichloride (61.19g, 460.38mmol) to the reaction mixture. Then, while maintaining the reaction temperature under an argon atmosphere at less than -10C , 4-N,N- dimethylpyridine (DMAP) (78.7g, 644.53mmol) added over 30 minutes. The mixture was then stirred for about 2 hours at 0C , the reaction is terminated. The reaction mixture was quenched by addition of water 400 ml, and extracted once the aqueous phase with methylene chloride. The combined organic phase organic phase was washed with 1N HCl 350ml. After that, the organic phase was filtered through Celite, and concentrated. The residue, isopropanol: with water and recrystallized, obtaining 2b (92g, 78% yield) as a white solid.
