The syntheses of trans-5-chloro-2, 3, 3a-12b-tetrahydro-2-methyl-1H-dibenz [2, 3:6, 7] oxepino [4, 5-c]pyrrole (Org 5222), a potential antipsychotic compound, labelled with 3H, 14C and 36C1 and trans-5-chloro-2, 3, 3a, 12b-tetrahydro-1H-dibenz [2, 3:6, 7]-oxepino [4, 5-c] pyrrole (Org 30526) labelled with 3H are described. 3H-labelled Org 5222 of low specific activity was prepared by a base catalyzed exchange with tritiated water of an amide precursor, 3H-labelled Org 5222 with a high specific activity by a catalytic reductive dehalogenation. 3H-labelled Org 30526 was prepared both by demethylation of 3H-Org 5222 and by catalytic reductive iodination of 11-iodo-Org 30526. 14C-labelled Org 5222 was synthesized in 6 steps using 14C-sarcosine as starting material. 36C1-labelled Org 5222 was prepared by diazotation reaction in the presence of H36C1.
反式-5-氯-2, 3, 3a-12b-四氢-2-甲基-1H-二苯并[2, 3:描述了用 3H、14C 和 36C1 标记的潜在抗精神病化合物--反式-5-氯-2,3,3a,12b-四氢-1H-二苯并 [2,3:6,7] 氧杂卓 [4,5-c] 吡咯(Org 5222)和用 3H 标记的反式-5-氯-2,3,3a,12b-四氢-1H-二苯并 [2,3:6,7] 氧杂卓 [4,5-c] 吡咯(Org 30526)。低比活度的 3H 标记 Org 5222 是通过碱催化三价水交换酰胺前体制备的,而高比活度的 3H 标记 Org 5222 则是通过催化还原脱卤制备的。3H 标记的 Org 30526 是通过 3H-Org 5222 的去甲基化和 11-iodo-Org 30526 的催化还原碘化制备的。14C 标记的 Org 5222 以 14C 肌氨酸为起始原料,分 6 步合成。36C1 标记的 Org 5222 是在 H36C1 存在下通过重氮反应制备的。
