The title compound, was prepared in accordance with the general method of example 4, step 2 using 2-amino-4-methylthiazole instead of 2-chloro-4-aminopyridine to yield 6-Methyl-2-(4-methyl-thiazol-2-ylcarbamoyl)-pyridin-3-yl]-carbamic acid tert-butyl ester as a light yellow solid. MS (ISP): m/e=349.0 (M+H+). Boc-deprotection as described in example 4 step 3 yielded 3-Amino-6-methyl-pyridine-2-carboxylic acid (4-methyl-thiazol-2-yl)-amide as an off-white solid, MS (ISP): m/e=249.4 (M+H+). Palladium catalysed arylation with 3-Bromopyridine as described in example 4 step 4 yielded the final product as a yellow solid, MS (ISP): m/e=326.0 (M+H+).
