Reaction Steps
To an ethylene glycol dimethyl ether (50 mL) solution of ethyl 3-{((1Z)-2-cyano-2-(3-pyridyl)vinyl)[(methoxycarbonyl)methyl]amino}propanate (6.236 g) was added 1,8-diazabicyclo[5,4,0]-7-undecene (3.590 g), and the mixture was stirred at 60° C. overnight. The reaction solution was cooled to room temperature and neutralized with acetic acid, and the solvent was distilled off under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=1/5), to obtain the title compound (4.380 g, yield 70%). The NMR data and ESI/MS data of the compound are given below.
