Procedure

EDCI (0.32 g) was added to the solution of (2Z)-3-(5-chloro-6-{[(3R)-1-(cyclohexylmethyl)-3-piperidinyl]amino}-3-pyridinyl)-2-fluoroacrylic acid (0.68 g), O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (0.24 g), and HOBT (0.28 g) in DMF (13.6 ml) and the mixture was stirred at ambient temperature for 20 hr. The reaction mixture was poured into a mixture of AcOEt and aq NaHCO3. The separated organic layer was washed with water, dried over magnesium sulfate and evaporated in vacuo. The residue was crystallization with solution of iPE and hexane to give (2Z)-3-(5-chloro-6-{[(3R)-1-(cyclohexylmethyl)-3-piperidinyl]amino}-3-pyridinyl)-2-fluoro-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (0.57 g).
