To a solution of methyl (2E)-3-[5-({(3R)-1-[2-(dimethylamino) benzyl]-3-pyrrolidinyl}amino)-2-pyrazinyl]acrylate (235 mg) in MeOH (1.9 mL) was added 1N NaOH aq. (1.2 mL), which was stirred at 55° C. for 1 hour. To the reaction mixture was added 1N—HCl aq. (1.2 mL), and evaporated in vacuo to give a crude (2E)-3-[5-({(3R)-1-[2-(dimethylamino)benzyl]-3-pyrrolidinyl}amino)-2-pyrazinyl]acrylic acid as, a brown solid (0.310 mg). This was used next reaction without purification.
