After the addition, the mixture is heated at 100 0C for 18 hours then the mixture is extracted three times with ethyl acetate. The combined organic layers are washed with water and brine then is dried over magnesium sulfate. The solvent is removed under reduced pressure and the residue is purified by flash chromatography (heptane/ethyl acetate =3:1 ) to give diethyl 6-aminopyrimidine-2,4-dicarboxylate; HPLC Retention time 0.89 minutes (condition C); MS 240.3 (M+1 ).Next, To a stirred solution of tert-butyl nitrite (268 mg, 2.34 mmol.) in DMF (5 mL) at 60 0C is added a solution of diethyl 6-aminopyrimidine-2,4-dicarboxylate (280 mg, 1 .17 mmol) in DMF (0.5 mL) dropwise and mixture is heated at 60 0C for 18 hours. The mixture is cooled to room temperature and poured into 1 N HCI (10 ml_). The mixture is extracted three times with ethyl acetate and the combined organic layers are washed with water and brine then is dried over magnesium sulfate. The solvent is removed under reduced pressure and the residue is purified by flash chromatography (heptane/ethyl acetate =4:1 ) to give diethyl pyrimidine-2,4-dicarboxylate.Next, to a stirred solution of diethyl pyrimidine-2,4-dicarboxylate (130 mg, 0.58 mmol) in MeOH (3 ml_) is added 1 N NaOH (2 ml_) and the mixture is stirred at room temperature for 3 hours. The solution is carefully acidified with 1 N HCI and the solvent is removed under reduced pressure to give pyrimidine-2,4-dicarboxylic acid. This is used as is in subsequent reactions. |

After 15 minutes calcium chloride (373 mg, 2.97 mmol) is added and the reaction mixture is warmed to room temperature. The reaction mixture is dried to a yellow solid and subjected to soxhlet extraction with ethanol. The ethanol is evaporated to a white solid. The product is crystallized from Methanol and water or purified by silica gel flash column chromatography to give the title compound. | |

56% | In N,N-dimethyl-formamide; at 100℃; | Step A. Under an argon atmosphere a solution of commercially available [l,3,5]triazine-2,4,6-tricarboxylic acid triethyl ester (818 mg) and 3-aminopyrazole (460 mg) in dry DMF (8 mL) was heated to 1000C overnight and then concentrated. The remaining residue was dissolved in CHCl3, washed with 10% aqueous citric acid and saturated aqueous NaCl, dried (MgSO4), filtered, concentrated and purified by chromatography (silica, CH2Cl2ZMeOH) to afford the title compound as a colorless solid (409 mg, 56%).
