실험 절차
2-{5-Methyl-2-[3-(4-methylpiperazin-1-yl)-propylamino]-pyrimidin-4-yl}-benzo[b]thiophene-6-carboxylic acid methyl ester (1.31 g, 2.98 mmol) is dissolved in methanol (30 mL), THF (30 mL) and water (10 mL) and lithium hydroxide solution (4.6 mL of 2.0 M solution) is added. The solution is heated at 70° C. for 4.5 hours and 5 N HCl (9 mL) is added in one portion while still heating the solution. The solution is cooled to room temperature and the resulting solid is filtered and washed with methanol. The solid is dried at 60° C. in a vacuum oven for 4 hours to give the title compound (1.43 g, 97% yield). ES+(m/z) 426 [M+H].
