Reaction Steps

A mixture of tert-butyl (3R)-3-({5-[(1E)-3-ethoxy-3-oxo-1-propen-1-yl]-2-pyridinyl}amino)-1-pyrrolidinecarboxylate (600 mg) and 1N NaOH solution (3.3 ml) in MeOH (10 ml) and THF (10 ml) was stirred at 70-75° C. for 2 hours. The reaction mixture was evaporated in vacuo and the residue was dissolved in a mixture of AcOEt and H2O. The aqueous solution was adjusted to PH4.5 and extracted with AcOEt and THF. The organic layer was washed with brine and dried over MgSO4. The solvent was concentrated in vacuo and the precipitate was collected by filtration to give (2E)-3-(6-{[(3R)-1-(tert-butoxycarbonyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid (0.45 g).
