Participants

Reaction Steps

To a solution of compound (20) (1.85 g, 4.62 mmol) in dry CHCl3 (50 ml) were added triethylamine (1.93 ml, 1.40 g, 13.86 mmol) and 4-nitrobenzylbromide (0.99 g, 4.62 mmol). After stirring the mixture at an ambient temperature for 10 hours, the solvent was removed under reduced pressure, and the residue was purified via alumina (basic) column chromatography. Extraction with ethyl acetate/methanol (10:2) gave a solidified clear oily compound (21) (1.98 g, 80% yield).
