Following the procedure as described in Example 2, making variations as required to replace pyridin-3-ylmethanamine with (3-methyl-1H-pyrazol-5-yl)methanamine to react with 2-(1-(4-fluorobenzyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-4-methylthiazole-5-carboxylic acid instead of (S)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as an off-white solid in 31% yield: mp 234-235° C.
