YieldReaction ConditionsOperation in experiment
Step A: Preparation of 2-[[[3-(l,l-dimethylethyl)-l-ethyl-lH-pyrazol-5-yl]carbonyl]ammo]-4- pyrimidinecarboxylic acidTo a solution of 3-(l,l-dimethylethyl)-l-ethyl-lH-pyrazol-5-carboxylic acid (12.8 g, 65mmol) in DCM (100 ml) were added oxalyl chloride (16 g, 131 mmol) and DMF (3 drops). <n="36"/>- 35 -The solution was stirred for 1.5 h and the solvent and excess oxalyl chloride removed under reduced pressure.The resulting residue was taken up in DCM (25 ml) and added to a well stirred mixture of <strong>[2164-66-1]methyl 2-amino-4-pyrimidinecarboxylate</strong> (5.0 g, 33 mmol), triethylamine (18.2 ml, 131 5 mmol) and DMAP (0.2g) in DCM (125 ml) and then stirred overnight at 2O0C and heated under reflux for 2 h. The reaction mixture was cooled to room temperature, poured into water (100 ml), extracted with DCM (2 x 70 ml) and the extracts dried over anhydrous magnesium sulphate. Removal of the solvent gave the residue as a gum. The gum was taken up in a mixture of sodium hydroxide (7.0 g) and methanol (75 ml) and the10 mixture stirred for 3 h at 2O0C. The solvent was removed and the residue partitioned between water (300 ml) and ethyl acetate. The aqueous phase was neutralised with c. HCl, the precipitate extracted into DCM, dried over anhydrous magnesium sulphate. Removal of the solvent gave a crude residue which was washed with DCM (30 ml) for 10 min at 200C and filtered to give the title acid as a white solid (0.7g). This was used in the next step without15 further purification .
