[Uses]

7H-Pyrrolo[2,3-d]pyrimidine is used as an organic synthesis or pharmaceutical intermediate. Its pyrrolo[2,3-d]pyrimidines are important parent heterocyclic compounds and are synthetic raw materials for the preparation of anti-rheumatoid arthritis and anti-tumour drugs.
[Synthesis]

4-Chloro-7H-pyrrolo[2,3-d]pyrimidine

3680-69-1

7H-Pyrrolo[2,3-d]pyrimidine

271-70-5

4-Chloro-7H-pyrrolo[2,3-d]pyrimidine (compound 1001) (130 mg, 0.847 mmol) was used as a raw material and dissolved in 3 mL of methanol. The hydrogenation reaction was carried out by adding 10% Pd-C catalyst under hydrogen atmosphere at 1 atmosphere for 16 hours. Upon completion of the reaction, the reaction solution was concentrated to dryness to afford 7H-pyrrolo[2,3-d]pyrimidine (Compound 1002) in 100 mg yield and 98% yield. The product was characterized by 1H-NMR (CD3OD): δ 9.4 (s, 1H); 9.1 (s, 1H); 7.9 (s, 1H); 7.1 (s, 1H).
