Ethanesulfonylchloride, 2-chloro- → 9-[4-(3-Methylphenoxy)phenyl]-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide

Participants

Reaction Steps

To a suspension of NaH (60%, 370 mg) in THF (dry) (25 mL) was added 2-chloroethanesulfonyl chloride (0.583 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-(3-methylphenoxy)phenyl)pyridin-2-amine (511 mg) in THF (dry) (40 mL) was added at 0° C. and the mixture was stirred at room temperature overnight. The mixture was quenched with water at 0° C. Water, EtOAc and IPE were added and the precipitates were collected, washed with water/EtOAc, dried in vacuo to give the title compound (514 mg) as a white solid. A part of this was recrystallized from MeCN/IPE.
