B. Jiang, PREPARATION OF -[(ARYL)METHYL]SULFINYL-1H-IMIDAZO[4,5-C]PYRIDINE, USEFUL AS AN ANTIOSTEOPOROTIC AGENT, Organic process research & development, 2(6), 1998, pp. 425-427
A new process for the oxidation of 2- [(aryl)methyl]thio-1H-imidazo[4,
5-c]pyridine to 2-[(aryl)methyl]sulfinyl-1H-imidazo[4,5-c]pyridine was
achieved using NCS under mild condition. The reaction selectively aff
ords the desired sulfoxide as the only product in high yield without f
urther oxidation to the sulfone side product.
