実験手順
The first crystals of methyl N-[3-(6,7-dimethoxy-2-methylaminoquinazolin-4-yl)phenyl]terephthalamic acid hydrate can be produced by dissolving methyl N-[3-(6,7-dimethoxy-2-methylaminoquinazolin-4-yl)phenyl]terephthalamic acid in acetone and precipitating crystals from the solution. More particularly, the first crystals of methyl N-[3-(6,7-dimethoxy-2-methylaminoquinazolin-4-yl)phenyl]terephthalamic acid hydrate can be produced by dissolving methyl N-[3-(6,7-dimethoxy-2-methylaminoquinazolin-4-yl)phenyl]terephthalamic acid in acetone at room temperature or under heating and slowly cooling the solution to 4° C. to room temperature to precipitate crystals from the solution.
