To a solution of (2E)-3-(4-{[(3R)-1-(4-chlorobenzoyl)-3-pyrrolidinyl]amino}phenyl)acrylic acid (103 mg) in DMF (2 mL) was added O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (35.8 mg), HOBt (48.8 mg), and EDCI (56.1 mg) and the resulting mixture was stirred at ambient temperature for 3 hours. The reaction mixture was diluted with water and extracted with AcOEt. The organic phase was washed with sat NH4Cl aq solution, sat NaHCO3 aq solution, and brine, and dried over Na2SO4. The solvent was removed in vacuo and the residue was purified by preparative thin layer chromatography (chloroform:methanol=10:1) to give (2E)-3-(4-{[(3R)-1-(4-chlorobenzoyl)-3-pyrrolidinyl]amino}phenyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (76 mg) as pale yellow form.
