Reaction Steps

The dimethyl piperazine from step A (80 mg, 0.32 mmol), phenyl N-3-bromophenyl-N′-cyanocarbamimidate, from Example 5, step A, (100 mg, 0.32 mmol) and N,N-diisopropylethylamine (0.20 ml) were added to isopropanol (10 ml). The mixture was heated at 150° C. for 20 min in a microwave, then concentrated under vacuum. The material was purified prep HPLC (Sunfire C18 30×250 mm column, 10-100% MeCN:H2O (10 mM NH4OAc), 18 min., 45 ml/min) to give (E)-N-(3-bromophenyl)-N′-cyano-2,5-dimethyl-4-(5-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperazine-1-carboximidamide (29 mg, 0.062 mmol, 19%).
