Participants

Reaction Steps

2-[4-[[(3S)-1-Benzyl-3-pyrrolidinyl]oxy]phenyl]-3-(7-cyano-2-naphthyl)propionic acid ethyl ester (5 g, 9.9 mmol) was heated and dissolved in ethanol (15 ml), and the resultant solution was cooled to room temperature with stirring to settle crystals. Subsequently, sodium ethoxide (100 mg, 1.5 mmol) was added thereto, followed by stirring at the same temperature for one hour, then sodium ethoxide (100 mg, 1.5 mmol) was further added, followed by stirring for 15 hours. The crystals were collected through filtration to obtain 3.9 g of the title compound (77% yield). The obtained crystals had a diastereomer purity of 47% under HPLC analysis conditions.
