Participants

Reaction Steps

Following the procedure of Example 2, making variations only as required to use butoxyacetic acid in place of benzyloxyacetic acid to react with [4-(6-aminopyridazin-3-yl)piperazin-1-yl](2-trifluoromethylphenyl)methanone, the title compound was obtained as a white powder (40.8% yield). 1H NMR (300 MHz, CDCl3) δ 9.19, 8.35, 7.72, 7.55, 7.33, 7.03, 4.05, 3.94, 3.60, 3.31, 1.64, 1.43, 0.93.
