実験手順

Combined 6-(4-(4-cyano-2-methylphenyl)-5-hydroxy-1H-pyrazol-1-yl)nicotinic acid (0.5 g, 1.561 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.449 g, 2.342 mmol), HOBT (0.359 g, 2.342 mmol) and 1-propylpiperazine dihydrobromide (0.543 g, 1.873 mmol) in DMF (1.56 mL) and added DIPEA (1.09 mL, 6.24 mmol) to give an orange solution. After stirring for 20 minutes the reaction mixture was heated to 60° C. for 3 hours, then was diluted with water (5 mL) and acidified with 6N aqueous hydrochloric acid to pH 6 and stirred at ambient temperature for 30 minutes to give a solid. The solid was collected by filtration, washed with water (3 mL) and suspended in ACN (10 mL). The suspension was treated with 1N aqueous hydrochloric acid (2 mL) and heated to 40° C. Ethyl ether was then added until the mixture became slightly cloudy (˜8 mL) and then allowed to cool to ambient temperature to give a solid, and then cooled in an ice bath for 30 minutes. The solid was collected by filtration and dried in vacuum at 80° C. for 1.5 hour to give the title compound as a hydrochloride salt (81.3 mg, 0.174 mmol, 11.15%). 1H NMR (400 MHz, DMSO-d6) δ ppm 0.92 (t, J=7.45 Hz, 3H) 1.64-1.79 (m, 2H) 2.43 (s, 3H) 2.81-3.20 (m, 4H) 3.21-4.90 (m, 6H) 7.67 (d, J=7.58 Hz, 1H) 7.71-7.91 (m, 2H) 7.93-8.74 (m, 4H) 10.75 (br. s., 1H) 13.23 (br. s., 1H); [M+H]+ 431.
