  [Graphics]An efficient process to produce kilogram quantities of a key, argininylbenzo[d]thiazole intermediate was developed for the preparation of the tryptase inhibitor RWJ-56423. A variety of activated arginine esters and benzo[d]thiazole nucleophiles were evaluated as coupling partners. Our work led to the selection and optimization of an argininyl imidazolide ester and benzothiazol-2-yl MgCl nucleophile. This paper focuses on the preparation, use, and stability of the benzothiazol-2-yl Grignard reagents.

  Optically pure amines were synthesized effectively by Lewis acid-catalyzed triethylsilane reduction of N-acyl-α-methoxyalkylamines which were readily obtained by anodic oxidation of N-acyl-α-amino acids. This method was also applied to the conversion of an N-acylpeptide into the corresponding optically pure amine derivative.
