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).

with hydrogen;palladium 10% on activated carbon in methanol under 760.051 Torr; for 16 h;

Steps:

1a; 1.i
As shown in Figure 1-step i, 4-chloro-7H-pyrrolo[2,3-d]pyrimidine(compound 1001) (130 mg, 0.847 mmol) was dissolved in 3 mL of methanol and hydrogenated under 1 atm of hydrogen over Pd-C 10% for 16 hours. Concentration to dryness provided 100 mg (98%) of 7H-pyrrolo[2,3-d ]pyrimidine [compound 1002, 1H-NMR(CD3OD): δ 9.4 (s, IH); 9.1 (s, IH); 7.9 (s, IH); 7.1 (s, IH)].
