摘要: [14C] and [13C]MON 37500 labeled in the imidazopyridine (Im) ring system were synthesized seven steps an overall yield of 39 28%, respectively, from [2-14C] [2-13C]chloroacetic acid. [14C]MON pyrimidine (Pd) was [2-14C]diethyl malonate four 48% yield. Lastly, [15N]MON prepared three 28% [15N]ammonium chloride. Copyright © 2005 John Wiley & Sons, Ltd.
