4-Chloroquinazoline-6-carboxylic acid methoxymethylamide (XIV-1, 5.78 g) was dissolved in tetrahydrofuran (100 ml), and 5.39 g of 3-chloro-4-(pyridin-2-ylmethoxy)aniline was added, followed by stirring at 60° C. for 1 hour. A precipitate was filtered, and washed with tetrahydrofuran to obtain 4-(3-chloro-4-(pyridin-2-ylmethoxy)phenylamino)-quinazoline-6-carboxylic acid methoxymethylamide (XI-2, 7.87 g) as a white solid. The filtrate was allowed to stand at room temperature, and the resulting precipitate was collected by filtration, to newly obtain 2.21 g of XI-2.
