実験手順
265 mg (1 mmol) of 4-amino-N-(2-diethylamino-ethyl)-2-methoxy-benzamide is introduced into 15 ml of methylene chloride and mixed in succession with 111 mg (1.1 mmol) of triethylamine and 126 mg (1.1 mmol) of methanesulfonic acid chloride. It is stirred for 2 hours at room temperature and then allowed to stand overnight. It is then mixed with 25 ml of saturated sodium bicarbonate solution and shaken out three times with 25 ml each of methylene chloride. The collected organic phase is dried, filtered and concentrated by evaporation. The residue is chromatographed on 10 g of basic silica gel (Isolute flash Si NH2) with a gradient from cyclohexane:ethyl acetate=100:0 to 50:50. 232 mg (52.6% of theory) of N-(2-diethylamino-ethyl)-4-(bismethanesulfonylamino)-2-methoxy-benzamide with a melting point of 144.1° C. is obtained.
