The enantiomers of [3-3H]-2-[[4-[(7-chloro-4-quinolinyl)amino]pentyl]ethylamino]ethanol,[3-3H]-hydroxychloroquine, (R)-8 and (S)-8, have been prepared in two steps from the known precursors 4,7-dichloro-3-iodoquinoline, 4, and the enantiomers of 2-[(4-aminopentyl)ethylamino]ethanol, (R)-2 and (S)-2, by formation of the enantiomers of 2-[[4-[(7-chloro-3-iodo-4-quinolinyl)amino]pentyl]ethylamino]ethanol, (R)-3 and (S)-3, and subsequent reductive deiodination with tritium gas over 10% palladium on charcoal.
由已知前体 4,7-二氯-3-碘喹啉 4 和 2-[(4-氨基戊基)乙氨基]乙醇的对映体分两步制备了[3-3H]-2-[[4-[(7-氯-3-碘-4-喹啉基)氨基]戊基]乙氨基]乙醇、[3-3H]-羟基氯喹的对映体(R)-8 和 (S)-8、(R)-2 和 (S)-2,形成 2-[[4-[(7-氯-3-碘-4-喹啉基)氨基]戊基]乙氨基]乙醇的对映体 (R)-3 和 (S)-3,然后在 10% 钯炭上用氚气还原脱碘。
