2-Naphthalenesulfonyl chloride → 1-(2-Ethylphenyl)-4-(2-naphthylsulfonyl)piperazine

Participants

Reaction Steps

Sulfonylation of 1-(2-ethylphenyl)piperazine (293 mg, 1.54 mmol) with naphthalene-2-sulfonyl chloride (350 mg, 1.54 mmol) was carried out according to a similar procedure described for example 3A using anhydrous dichloromethane (5 mL) as solvent and diisopropylethylamine (0.670 mL, 3.85 mmol) as base. 1-(2-ethylphenyl)-4-(2-naphthylsulfonyl)piperazine was obtained in 99% yield (579 mg) as white solid.
