실험 절차

The obtained (R)-2-mercaptobutyric acid was purified by distillation and then reacted with ammonium acetate and 1-methyl-4-piperidone in boiling cyclohexane. The crude reaction mixture was analyzed by GC on a chiral column and found to contain AF267A accompanied by a small (2–3%) amount of AF267B.
