实验过程

Resolution of enantiomers of racemic 4-(5-chloro-2-fluorophenyl)-2-(3-hydroxyphenyl)-1-(2-methylalanyl)-2,5-dihydro-1H-pyrrole (174) by chiral normal-phase HPLC (Chiralcel OD column: 0.1% diethylamine in 10% ethanol in hexanes initially, grading to 30% ethanol in hexanes) provided (2S)-4-(5-chloro-2-fluorophenyl)-2-(3-hydroxyphenyl)-1-(2-methylalanyl)-2,5-dihydro-1H-pyrrole (17-5) as the first eluting, minus (−) enantiomer.
