Following the procedure as described in Example 40, making variations as required to replace 1-(5-acetyl-4-methylthiazol-2-yl)-3-(4-(piperidine-1-carbonyl)benzyl)imidazolidin-2-one with 3-((3-(5-acetyl-4-methylthiazol-2-yl)-2-oxoimidazolidin-1-yl)methyl)-N-methylbenzamide to react with N,N-dimethylacetamide dimethyl acetal and further with hydrazine monohydrate, the title compound was obtained as a colorless solid in 54% yield: nip 259-261° C. (ethyl acetate); 1H NMR (300 MHz, DMSO-d6) δ 7.73-7.62 (m, 2H), 7.42-7.34 (m, 2H), 6.32 (br s, 1H), 4.51 (s, 2H), 4.13-4.04 (m, 2H), 3.49-3.41 (m, 2H), 2.97 (d, J=4.8 Hz, 3H), 2.60 (s, 3 H), 2.45 (s, 3H); MS (ES+) m/z 373.1 (M+1).
