Water → 4-{[4-(Dodecyloxy)benzoyl]oxy}benzoic acid

Participants

Reaction Steps

The 4-(4-n-dodecoxybenzoyloxy)-benzaldehyde produced in step A4 (17.4 g) was dissolved in acetic acid (60 ml) and treated with a solution of chromium trioxide (12.7 g) dissolved in 50% acetic acid added dropwise over 20 minutes at 40° C. After stirring at 45°-50° for 20 hours, water (150 ml) was added and the mixture stirred for 3 hours. The product separated and was recrystallised from acetic acid (55 ml) to give 4-(4-n-dodecoxybenzoyloxy)-benzoic acid (15 g, 83% theory).
