実験手順

Ethyl 1-[5-[7-amino-2-(ethylcarbamoylamino)-1,3-benzothiazol-5-yl]pyrimidin-2-yl]-4-methyl-piperidine-4-carboxylate (159 mg, 0.27 mmol), pyrimidine-2-carboxylic acid (64.2 mg, 0.52 mmol) and diisopropylethylamine (271 mg, 2.1 mmol) were dissolved in DMF (5 mL). The reaction was purged with N2 then HATU (197 mg, 0.5 2 mmol) was added and the reaction stirred at rt for 18 h. The DMF was removed under reduced pressure and the resulting residue diluted with water and extracted with EtOAc. During the work up a solid precipitated which was collected by filtration and dried in the vacuum oven to provide the crude product (100 mg, 66% yield).
