Popis: The development of a manufacturable synthesis of LY213829 (4-thiazolidinone-5-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl] methyl) is described. Rather than reduction to eliminate the thiocarbonyl from the rhodanine moiety, the new route utilizes a novel concurrent ring opening with ammonia and re-cyclization with formaldehyde. This change obviates a potentially problematic zinc solid waste stream.
