Hexane → HCID 58452903, compound

Participants

Reaction Steps

An (R,S) mixture of the title compound was obtained by performing substantially the same reaction as in Examples 4-207 and 4-208(2) except for using 6-{(E)-1-(4-tert-butylphenyl)-2-[(2R)-5-oxopyrrolidin-2-yl]ethenyl}-3-methoxypyridin-2(1H)-one obtained in Example 4-164. This was preparatively isolated by a chiral HPLC column (CHIRALCEL OD-H, hexane:ethanol=50:50 v/v, 40° C., 7.0 mL/min, 210 nm) to give one diastereomer (A) of the title compound as a colorless amorphous (9.5 mg) and the other diastereomer (B) of the title compound as a colorless powder (11.9 mg).
