실험 절차

Diisopropylethylamine (0.22 mL, 1.3 mmol) was added to a suspension of 1-(2-aminoethyl)-6-(2,4-dimethoxyphenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one hydrochloride (181.6 mg, 0.528 mmol) (the product of Example 6) and 1H-pyrazole-1-carboxamidine hydrochloride (90.6 mg, 0.618 mmol) in DMF (0.55 mL). After heating for 1 h at 55° C., the reaction mixture was cooled to ambient temperature, diluted with EtOH (1.6 mL), and the solid product collected by vacuum filtration, rinsing with additional EtOH. The isolated solid was re-suspended in EtOH (2.1 mL) for 3 h at r.t. before being collected again by vacuum filtration and rinsing with additional EtOH. The desired product was obtained, after drying, as a colorless solid. Solubility data for this product is consistent with it being in its zwitterionic form.
