Dimethyl Sulfoxide → HCID 21876992, compound

Participants

Reaction Steps

Solid potassium tert-butoxide (113 mg, 1 mmol) was added to a solution of 4-(4-ethanesulfonylaminobenzyl)-phenylamine (290 mg) (prepared as described in Example 7) in dimethyl sulfoxide (2 mL). The mixture was stirred and methyl iodide (0.1 mL, 1.5 mmol) was added. After 1 hour, the reaction mixture was poured into water and extracted with diethyl ether (2×). The organic phase was dried on potassium carbonate, evaporated and chromatographed on silica gel, eluting with dichloromethane/acetone, to give 4-[4-(ethanesulfonyl)methylaminobenzyl]-phenylamine (200 mg, 66%) as a yellow solid.
