Reaction Steps

Methyl 4-nitroheneicosanoate (5a) (147 mg, 0.38 mmol) was dissolved in 1,2-dimethoxyethane (DME) (2 mL) and sat. aq LiOH solution (2 mL) was added. The mixture was left for 24 h, then it was acidified with dilute HCl (10%, 10 mL) and the mixture was extracted with EtOAc (2×10 mL). The extracts were concentrated under a stream of dry N2 and the residue was subjected to flash column chromatography on silica (Et2O/hexane, 100/20, then Et2O/hexane/HOAc, 60/40/1) to afford 4-nitroheneicosanoic acid (6a) (121 mg, 85%) as a white solid; mp 55-56° C.
