And the article contained the following:

Fiduxosin (I) is under development for the treatment of benign prostatic hyperplasia. A convergent strategy required methodologies for preparation of an enantiomerically pure 3,4-cis-disubstituted pyrrolidine and a 2,3,5-trisubstituted thienopyrazine in a regiospecific manner. A [3+2] cycloaddition of an enantiopure azomethine ylide followed by a diastereoselective crystallization was employed to prepare the benzopyranopyrrolidine in high diastereomeric and enantiomeric purity. Conditions for reduction of an O-aryl lactone susceptible to epimerization were developed, and cyclization of the alc./phenol to the ether was accomplished in high yield. The thienopyrazine was prepared by condensation of Me thioglycolate and a regiospecifically prepared 2-bromo-3-cyano-5-phenylpyrazine. Conditions for effective halogen substitutive deamination to prepare regiospecific trisubstituted pyrazines is described. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Recommanded Product: 2-Aminomalononitrile 4-methylbenzenesulfonate
