실험 절차

A solution of 8-amino-3-phenylsulfonylquinoline (D5) (38.8 g, 137 mmol) in n-butanol (360 ml) was treated with bis-(2-chloroethyl)-methyl-amine hydrochloride (40 g, 138 mmol) and sodium carbonate (72 g, 0.68 mol). The mixture was heated to a vigorous reflux (˜100° C.) for 16 h then a further portion of bis-(2-chloroethyl)-methyl-amine hydrochloride (25 g, 86 mmol) introduced and heating continued for a further 4 h. The solution was cooled and a 1:1 mixture of saturated aqueous sodium bicarbonate and aqueous 10% sodium thiosulphate solution (2 L) added. Stirring was continued at ambient temperature for 16 h then the aqueous phase was extracted with dichloromethane (3×500 ml), the combined organic phase dried over magnesium sulphate, evaporated in vacuo and subjected to chromatography on a Biotage Flash 75 apparatus (1 kg Silica gel) to afford the title compound (E1) as the free base form (11.6 g), identical spectroscopically to that prepared by the first method.
