Reaction Steps
Steps are taken to avoid isomerization of 2-(bromomethyl)-maleic acid (3) to the corresponding fumarate analog by hydrolyzing the anhydride (2) in a dilute aqueous solution and neutralizing the diacid (3) immediately after complete hydrolysis. Any bromomethyl fumaric acid derivative formed is removed in purifying compound (4) as described in more detail below.
