Reaction Steps
A sample of 75 mg of fenoterol HBr was dissolved in 1.5 mL of 95/5/0.05 CH3CN/isopropanol/HNEt2 and applied in 100 μL injections to a CHIRALPAK® AD-H 10×250 mm 5 μm semi-preparative column using a waters 2690 Separations Module, PDA set to 280 nm. The eluting solvent was 95/5/0.05 CH3CN/isopropanol/HNEt2, 5 mL/min. Retention times for (S,S) and (R,R) isomers were 4.8 min and 7.8 min, respectively.
