Reaction Steps

To 7-bromo-4-chloro-5H-pyrrolo[3,2-d]pyrimidine (147 mg), N,N-dimethylformamide (10 mL) was added, and NaH (36 mg) was further added thereto, followed by stirring for 30 min. Subsequently, methyl iodide was added thereto, and the reaction mixture was heated to 50° C. and stirred for 2 hours. After completion of the reaction, the reaction mixture was mixed with ethyl acetate and washed with water. The washed mixture was dried over anhydrous sodium sulfate, and filtered and distilled under reduced pressure to obtain the title compound.
