Product 1

HCID 116680746-[4-(1-METHYL-1H-PYRROLE-2-CARBONYL)PIPERAZIN-1-YL]PYRIDAZINE-3-CARBOXYLIC Acid (2-CYCLOPROPYLETHYL)AMIDE

Procedure

Following the procedure of Example 9, making variations only as required to use 1-methyl-1H-pyrrole-2-carboxylic acid in place of 2,5-dichlorobenzoic acid to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (2-cyclopropylethyl)-amide, the title compound was obtained as a white powder (51.8% yield). 1H NMR (500 MHz, CDCl3) δ 8.07, 8.01, 7.00, 6.75, 6.40, 6.12, 4.00-3.80, 3.58, 1.52, 0.76, 0.48, 0.10. MS (ES+) m/z 383 (M+1).
