Cholesta-5,8-dien-3β-ol was synthesized in two steps by starting from 3β-acetoxycholesta-5,7-diene. Diethyl azodicarboxylate reacts with 3β-acetoxycholesta-5,7-diene to afford 3β-acetoxy-7α-(1,2-dicarbethoxyhydrazo)-cholesta-5,8-diene and 3β-acetoxy-7α-(1,2-dicarbethoxyhydrazo)cholesta-5,8(14)-diene. The former was then reduced with lithium in ethylamine to the title
