Reaction Steps

A solution of 1.0 g. of ethyl 4-hexadecanamido-1-methyl-2-pyrrolecarboxylate in 10 ml. of dry tetrahydrofuran is added dropwise to a solution of 6 ml. of 1 M borane in tetrahydrofuran under nitrogen and the pale yellow solution is heated to reflux overnight. After cooling and acidification with 1 N aqueous hydrochloric acid followed by neutralization with saturated sodium bicarbonate solution, the solution is extracted with ether. The extract is dried over anhydrous magnesium sulfate and evaporated. The residue is recrystallized from hexane to yield the product as a white solid.
