Yield:1434652-66-0 52%

Reaction Conditions:

with Venusil Chiral OD-H in ethanol;hexane;

Steps:

76 Synthesis of Compound 76.2.

Synthesis of Compound 76.2. [0802] The enantiomers of 76.1 (22 g) were resolved by chiral preparative HPLC under the following conditions (Gilson Gx 281): Column: Venusil Chiral OD-H, 21.1*25 cm, 5 μm; mobile phase: hexanes (0.2% TEA) and ethanol (0.2% TEA) (hold at 10% ethanol (0.2% TEA) for 13 min); detector: UV 220/254 nm. 11.4 g (52%) of 76.2 were obtained as a white solid.
