2,5,8,11,14,17,20-Heptaoxadocosan-22-oic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The product of step (a) (4.54 g) was dissolved in an aqueous sodium hydroxide solution (0.1M) (45 ml) and the reaction was stirred at room temperature for 20 hours. The reaction mixture was acidified to pH 2 by the addition of hydrochloric acid (2M), then this was diluted with brine (300 ml) and extracted with dichloromethane (3×300 ml). The combined organic layers were dried and the solvent removed in vacuo to give the title compound as a yellow oil (3.75 g). extracted with dichloromethane (3×300 ml) The combined organic layers were dried the solvent removed in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was synthesized by a condensation method similar to that of Step A of Example 3-1 using {2-[2-(2-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}ethoxy)ethoxy]ethoxy}acetic acid instead of Boc-Sar-OH and 7-((S)-5-hydroxymethyl-2-oxooxazolidin-3-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one obtained in Step B of Example 1-13 instead of 7-((R)-5-hydroxymethyl-2-oxooxazolidin-3-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one obtained in Step B of Example 1-14. However, {2-[2-(2-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}ethoxy)ethoxy]ethoxy}acetic acid was synthesized by a method similar to that of Step A of Example 4-39 using hexaethylene glycol monomethyl ether instead of pentaethylene glycol monobenzyl ether.
