Procedure
Partially purified 4-(5-chloro-1H,3H-benzo[de]isochromen-6-yl)-6-methanesulfinyl-pyrimidin-2-ylamine (99.9 mg) obtained in Step 5 of Example 314 was reacted with 3-mercapto-2-methylpropionic acid (133.0 mg) instead of mercaptoacetic acid using the same operation as the production method described in Step 6 of Example 314, and thus, 3-[2-amino-6-(5-chloro-1H,3H-benzo[de]isochromen-6-yl)-pyrimidin-4-ylsulfanyl]-2-methyl-propionic acid (115.4 mg) was obtained. Then, the obtained 3-[2-amino-6-(5-chloro-1H,3H-benzo[de]isochromen-6-yl)-pyrimidin-4-ylsulfanyl]-2-methyl-propionic acid (58 mg) was reacted with ammonium chloride (37.9 mg) using the same operation as the production method described in Step 6 of Example 314, and thus, 3-[2-amino-6-(5-chloro-1H,3H-benzo[de]isochromen-6-yl)-pyrimidin-4-ylsulfanyl]-2-methyl-propionamide (compound 321) (41.4 mg) was obtained as a white solid.
