Reaction Steps

To a solution of (S)-2-(tert-butoxycarbonyl)-4-hydroxybutanoic acid (72.6 g, 331 mmol) in EtOH (500 mL) was added dropwise dicyclohexylamine (73 mL, 364 mmol). The mixture was stirred for 2 hours at room temperature and then concentrated under reduced pressure. The white solid was dried under high vacuum and then triturated with ether (1000 mL).
