実験手順

Triethylamine (1.00 ml) was added to a solution containing 3-amino-4-{[2-(dimethylamino)ethyl]amino}-N-methylbenzamide (1.500 g) in chloroform (15 ml), and then stearoyl chloride (2.20 mnl) was added thereto while being cooled with ice. After being stirred for 2.5 hours, the reaction mixture was diluted with chloroform, washed with saturated sodium hydrogencarbonate aqueous solution and saturated brine successively, dried over sodium sulfate anhydride, and concentrated. Concentrated hydrochloric acid (5.3 ml) was added to a solution containing the residue (3.030 g) in ethanol (30 ml). After being stirred for 1.5 hours at 90° C., the reaction mixture was concentrated. The residue, with ethyl acetate added thereto, was washed with 1N sodium hydroxide aqueous solution and saturated brine successively, dried over sodium sulfate anhydride, and concentrated. The residue (3.737 g) was purified by silica gel column chromatography (silica gel 75 g, chloroform:methanol=50:1-30:1), thereby yielding the entitled compound (2.225 g) as pale yellow solid.
