YieldReaction ConditionsOperation in experiment
In 1-methyl-pyrrolidin-2-one; at 20 - 150℃; for 27h; [0100] A suspension of (5 g, 33 mmol) of guanine in 100 N-methy-2-pyrrolidinone NMP) and 20 ml acetic anhydride was heated to 150 C. for 3 hrs. The clear solution was stirred at room temperature for 24 hours. The precipitate was collected by filtration and washed with acetone. The N9,N2-diacetylated guanine (9) was dried and identified by 1H-NMR. [0101] M.P.=Decomp. 270 C. [0102] 1H-NMR (DMSO-d6): [0103] 12.1(bs, 1H-(N)), 8.53(s, 1H, H-(C8)); 2.91(s, 3H, Ac-(N9)); 2.31(s, 3H, -(N2-COCH3)). [0104] (5 g, 21.25 mmol) of (9) were suspended in 100 ml of dry pyridine and excess of diisopropyl ethylamine (DIEA). Then (5.91 g, 25.51 mmol) of diphenylcarbamoyl chloride ere added in portions. The reaction mixture turned orange immediately. Stirring continued for 2 hrs at r.t. then 20 nml if ice-cold water were added. The mixture was stirred for 10 minutes more and solvent was removed under reduced pressure. 100 ml of ethanol and 100 nml of water were added and the mixture was reflexed for 1.5 hr. After cooling to the room temperature, vigorous stirring continued for over night. The desired product (10) was collected by filtration and washed with 50 ml of ethanol, dried and characterized. [0105] M.P.=185 C. [0106] 1H-NMR (DMSO-d6): [0107] 10.7(s, 1H, H-(N2)); 8.55(s, 1H, H-(C8)); 7.61-7.38(m , 10H, aromatic); 2.28(s, 3H, -COCH3).
