Reaction Steps

A mixture of [3-(2-methanesulfonyl-pyrimidin-4-yl)-imidazo[1,2-a]pyrazin-8-yl]-(2-morpholin-4-yl-ethyl)-amine (from Example 50 supra) (200 mg, 0.50 mmol) and 2-chlorobenzylamine (281 mg, 1.99 mmol) was heated at 140° C. with stirring for 2 hours. The oil was purified by chromatography (silica gel, 10 g, 200-300 mesh, eluting with dichloromethane:methanol 50:1 to 20:1) to afford the crude product (110 mg). Then the crude product was purified by prep-HPLC. Several drops of concentrated HCl were added to the fractions with product. After sonicating for several minutes, solution was concentrated under reduced pressure to afford {3-[2-(2-chloro-benzylamino)-pyrimidin-4-yl]-imidazo[1,2-a]pyrazin-8-yl}-(2-morpholin-4-yl-ethyl)-amine; hydrochloride. (Yield 58 mg, 25.1%). 1H NMR (300 MHz, CD3OD): δ 8.72 (s, 1H), 8.51 (s, 1H), 8.35 (s, 1H), 7.59 (d, 1H, J=6.9 Hz), 7.46-7.28 (m, 5H), 4.75 (brs, 2H), 4.17 (brs, 2H), 3.93 (brs, 4H), 3.59-3.28 (m, 5H). LC-MS: [M+H]+ 466.
