Reaction Conditions

Reaction Steps

In a 50 ml sealed vessel, 1-[(2-chloro-1,3-thiazol-5-yl)methyl]-4-(2,3,5-trifluorophenyl)pyrrolidin-2-one 250 (0.1 g, 0.3 mmol) is dissolved in MeOH (3 ml). Sodium methoxide (3 mg, 0.06 mmol) and a solution of methylamine (0.09 g, 3 mmol) in MeOH are added. The vessel is closed and heated to 95° C. for 48 h. The reaction mixture is cooled to room temperature, the solvent is evaporated and the residue is taken up in CH2Cl2 and water. The aqueous phase is extracted twice with CH2Cl2, the combined organic phases are washed with brine, dried over MgSO4, filtered and concentrated in vacuo. The crude product is recrystallized from AcOEt to afford 185 mg of 1-{[2-(methylamino)-1,3-thiazol-5-yl]methyl}-4-(2,3,5-trifluorophenyl)pyrrolidin-2-one 252.
