A reaction mixture containing (2S)-2-(phenoxymethyl)oxirane (Example 15, 20.6 mmol, 1.0 eq.) and dibenzylamine (22.7 mmol, 1.1 eq.) in MeOH (100 mL) was heated at reflux overnight. The resulting solution was concentrated in vacuo and the crude product was purified by medium pressure column chromatography (Biotage 40S normal phase silica gel column, hexanes:EtOAc=10:1). The product was obtained as a colorless oil in 88% yield. MH+=348.3, Rf=0.42 (hexanes:EtOAc 6:1), retention time (LC-MS)=2.22 min.
