Reaction Steps

To a 100 ml flask was added 3-(2-methylpyridin-4-yl)-3-oxopropanenitrile 16.1.C, (465 mg, 2.9 mmole), 10 ml of MeOH and methyl hydrazine (249 μl, 7.26 mmole). The reaction was stirred at 70° C. for 8 hours at which time the solvent was removed with a stream of nitrogen. The crude product was purified by using a silica gel column (eluting with 5% MeOH in DCM) to give of 1-methyl-3-(2-methylpyridin-4-yl)-1H-pyrazol-5-amine 16.1.D as a yellow film (317 mg 49% yield). (Note: converted to HCl salt).
