실험 절차

1.30 ml (10.7 mmol) 2-chloro-4-methyl-aniline are placed in 30 ml of pyridine, combined with 2.67 g (10.5 mmol) 75% m 4-chlorobutyl-sulphonic acid chloride and stirred for 16 hours at ambient temperature. The reaction mixture is poured into water and extracted with ethyl acetate. The combined organic phases are washed with 6-molar hydrochloric acid, dried over sodium sulphate and evaporated down i. vac. The residue is purified by chromatography on silica gel (eluting gradient: petroleum ether/ethyl acetate=9:1→7:3).
