Sodium Hydroxide → HCID 18951537, compound

Participants

Reaction Steps

A solution of 1.5 g (2.3 mmol) of 3,5-bis[3-[4-(phenylmethoxy) phenoxy]propoxy]benzoic acid methyl ester (prepared in Example 46) and 1.2 ml (7.2 mmol) of 6N NaOH in 25 ml of methanol and 10 ml of dioxane was stirred at reflux under argon for 19 hours. The solvents were removed at reduced pressure, the residue was acidified and the product was extracted with ethyl acetate. The dried extract was concentrated to a solid which was recrystallized from acetone-hexane to give 1.37 g (93% yield, mp 139°-140°) of 3,5-bis[3-[4-(phenylmethoxy)phenoxy]propoxy]benzoic acid.
