HCID 594812454-methyl-2-(2-oxo-3-((tetrahydro-2H-pyran-2-yl)methyl)imidazolidin-1-yl)-N-(pyridin-3-ylmethyl)thiazole-5-carboxamideYield 40%

Procedure

Following the procedure as describe in Example 9, making variations as required to replace 2-(3-benzyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid with 4-methyl-2-(2-oxo-3-((tetrahydro-2H-pyran-2-yl)methyl)imidazolidin-1-yl)thiazole-5-carboxylic acid to react with 3-(aminomethyl)pyridine, the title compound was obtained as a white powder in 40% yield: mp 174-175° C.
