摘要
A "redox economical" strategy resulted in it concise, modular synthesis Of Compound 1, it potent Cathepsin S inhibitor. Starting from three building blocks, crude drug substance was prepared in a two-step sequence in high yield. Efficient purification of the crude drug Substance wits accomplished via the formation of an unusual monoethyl oxalate salt.
