Reaction Steps

The mixture of 3-(2-methanesulfonyl-pyrimidin-4-yl)-8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazine (from Example 46 supra) (150 mg, 0.402 mmol) and 3-chlorobenzylamine (228 mg, 1.608 mmol) was heated at 140° C. with stirring for 2 hours. The resulting oil was purified by chromatography (silica gel, 10 g, 200-300 mesh, eluting with dichloromethane:methanol, 30:1 to 10:1) to afford the crude product (120 mg). Then the crude product was purified by prep-HPLC. Several drops concentrated HCl were added to the fractions with product. After sonicating for several minutes, solution was concentrated under reduced pressure to afford (3-chloro-benzyl)-{4-[8-(4-methyl-piperazin-1-yl)-imidazo [1,2-a]pyrazin-3-yl]-pyrimidin-2-yl}-amine; hydrochloride. (Yield 45 mg, 25.8%).
