Reaction Steps

2-[4-[[(3S)-1-(tert-butoxycarbonyl)-3-pyrrolidinyl]oxy]phenyl]-3-(7-cyano-2-naphthyl)propionic acid ethyl ester (1.90 g, 3.7 mmol) was heated and dissolved in ethanol (6 ml), and the resultant solution was cooled to room temperature with stirring to settle crystals. Subsequently, sodium amide (22 mg, 0.6 mmol) was added thereto, followed by stirring at the same temperature for 30 minutes, then sodium amide (22 mg, 0.6 mmol) was further added, followed by stirring for 18 hours. The crystals were collected through filtration to obtain 1.48 g of the title compound (78% yield). The diastereomer purity of the crystals was 92.3%.
