Reaction Steps

3-{5-Cyano-6-[(2,2-dimethyl-propyl)-methyl-amino]-2-methanesulfinyl-pyrimidin-4-ylamino}-N-methoxy-4-methyl-benzamide (40 mg) and 1-methyl-homopiperazine (0.05 mL) in THF (0.5 mL) were heated in sealed tube at 75° C. for overnight. After the solvent was removed in vacuo, the residue was purified by silica gel column chromatography to afford the product (6.8 mg). MS (m/z): 495 (M+H).
