Procedure

The title compound was prepared from 3-tert-Butoxy-carbonylamino-6-methyl-pyridine-2-carboxylic acid methyl ester in accordance with the general method of example 4; step 2 using 1-(2-Methoxy-ethyl)-1H-pyrazol-3-yl amine instead of 2-chloro-4-aminopyridine to yield {2-[1-(2-Methoxy-ethyl)-1H-pyrazol-3-ylcarbamoyl]-6-methyl-pyridin-3-yl}-carbamic acid tert-butyl ester as a yellow oil, MS (ISP): m/e=376.5 (M+H+). Boc-deprotection as described in example 4 step 3 yielded 3-Amino-6-methyl-pyridine-2-carboxylic acid [1-(2-methoxy-ethyl)-1H-pyrazol-3-yl]-amide as a yellow oil, MS (ISP): m/e=276.3 (M+H+). Palladium catalysed arylation in accordance with the general method described in example 20 using 1-Bromo-3,5-difluorobenzene instead of 3-bromopyridine yielded the final compound as a light brown solid, MS (ISP): m/e=388.4 (M+H+).
