3-(3-Chloro-4-fluorophenyl)prop-2-enoic acid → 1H-Purine-2,6-dione, 3,7-dihydro-8-(2-(3-chloro-4-fluorophenyl)ethenyl)-1,3-diethyl-, (E)-

Reaction Steps

Substantially the same procedure as in Reference Example 70 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 3.01 g (15.1 mmol) of 3-chloro-4-fluorocinnamic acid. Then, the resultant crude crystals were recrystallized from tetrahydrofuran/water to give 560 mg (yield 32%) of Compound 176 as a white powder.
