HCID 11486820HCID 11486820, compound

Procedure

Following the procedure of Example 9, making variations only as required to use 2-chloropyridine-3-carboxylic acid in place of 2,5-dichlorobenzoic acid to react with 6-piperazin-1-ylpyridazine-3-carboxylic acid (2-cyclopropylethyl)amide, the title compound was obtained as a white solid (44% yield). 1H NMR (500 MHz, CDCl3) δ 8.50, 8.08, 7.99, 7.71, 7.37, 7.02, 4.05-4.13, 3.78-3.95, 3.34-3.60, 1.51, 0.71-0.80, 0.45-0.49, 0.08-0.12. MS (ES+) m/z 415 (M+1).
