実験手順

Working as in Example 1, but starting with 3-chloro-2-(7-chloro-1,8-naphthyridin-2-yl)-1-isoindolinone (6.9 g) in anhydrous dimethylformamide (70 cc), 3-diisopropylaminopropionic acid hydrochloride (4.4 g) and 1,8-diazabicyclo-[5.4.0]undec-7-ene (7.45 g), and after the residue obtained has been recrystallized successively, first in acetonitrile and then in ethanol, 2-(7-chloro-1,8-naphthyridin-2-yl)-3-oxo-1-isoindolinyl 3-diisopropylaminopropionate (2.7 g), m.p. 135° C., is obtained.
