A mixture of the product of Example 32, part B (0.250 g, 0.567 mmol), 1-(2-pyrimidyl) piperazine (0.121 g, 0.737 mmol), benzotriazol-1-yloxytris(dimethylamino)phosphoniumhexafluorophosphate (0.476 g, 1.08 mmol), 4-methylmorpholine (0.31 mL, 2.82 mmol) in DMF (6 mL) was heated at 65° C. for 5 h. The mixture was then diluted with ethyl acetate, washed with water, 1N NaOH solution, water, and brine. The solution was dried over anhydrous MgSO4 and concentrated under vacuum. The residue was purified using flash column chromatography (ethyl acetate) to provide the desired product (0.210 g, 63%) as a white solid: LC/MS RT=3.94 min; mass spectrum (M+H)+=587.42.
