実験手順

A mixture consisting of 500 mg of methyl 4-amino-3-[(3-oxo-6-pyridin-4-yl-2,3-dihydropyridazine-4-carbonyl)amino]benzoate, 6 ml of tetrahydrofuran (THF), 6 ml of methanol, 6 ml of water and 173 mg of lithium hydroxide is stirred at 50° C. for 5 hours. After cooling to room temperature, the pH is adjusted to 4-5 with 1N HCl, whereupon a precipitate separates out and is filtered off with suction and then washed with water and dried in vacuo.
