To a solution of (2E)-3-[5-({(3R)-1-[2-(dimethylamino)benzyl]-3-pyrrolidinyl}amino)-2-pyrazinyl]-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (236 mg) in MeOH (3.5 mL) was added 2N—HCl solution in EtOH (1.27 mL), which was stirred at room temperature for 1 hour. To the reaction mixture was dropwised IPE (9.4 mL), which was stirred further more 1 hour. The prepicitate was filtered to give (2E)-3-[5-({(3R)-1-[2-(dimethylamino) benzyl]-3-pyrrolidinyl}amino)-2-pyrazinyl]-N-hydroxyacrylamide trihydrochloride as a yellow powder (241 mg).
