Preparation of two ion-pair complexes of 3-dl-?-tocopherylcarbonyl-1-hexyl-pyridinium-[14C]-labeled cromolyn and 3-d-?-[5-methyl-3H] tocopherylcarbonyl-1-hexylpyridinium-cromolyn
摘要:
Ion-pair complexes of 3-dl-alpha-tocopherylcarbonyl-1-hexyl pyridinium-[C-14]-labeled cromolyn and 3-d-alpha-[5-methyl-H-3] tocopherylcarbonyl-1-hexylpyridinium-cromolyn have been prepared with radiochemical yields of 56.0 and 65.7 %, respectively.
