18-(Tert-butoxy)-18-oxooctadecanoic acid CAS NO: 843666-40-0 is a synthetic intermediate that has been used to synthesize semaglutide. It can be produced by the catalytic effect of ethyl bromoacetate on 18-hydroxyoctadecanoic acid in the presence of formamide and magnetic trifluoroacetic acid. The reaction time for the synthesis is 2 hours and produces high yields with a solid-phase synthesis. The product can be recycled, which reduces waste and cost. The product is also catalytically active and has a long shelf life.
