The present invention relates to the novel compounds Methyl 2-[(3S)-[3-[(2E)(7-chloro quinolin-2-yl)ethenyl]phenyl]-3-halopropyl]benzoates (IV) wherein the halo is chloro, bromo, iodo, starting from the known compound Methyl 2-[(3S)-[3-[(2E)-(7-chloroquinolin-2-yl)ethenyl]phenyl]-3-hydroxypropyl]benzoate (1). Reaction of Methyl 2-[(3S)-[3-[(2E)-(7-chloroquinolin-2-yl)ethenyl]phenyl]-3-hydroxypropyl]benzoate (1) with thionyl chloride or with methane sulfonyl chloride—lithium bromide or with trimethyl chlorosilane—sodium iodide in presence or absence of base gives Methyl 2-[(3S)-[3-[(2E)-(7-chloro quinolin-2-yl)ethenyl]phenyl]-3-halopropyl]benzoates.
本发明涉及一种新型化合物Methyl 2-[(3S)-[3-[(2E)-(7-氯喹啉-2-基)乙烯基]苯基]-3-卤代丙基]苯甲酸酯(IV),其中卤代物为氯、溴或碘。该化合物由已知化合物Methyl 2-[(3S)-[3-[(2E)-(7-氯喹啉-2-基)乙烯基]苯基]-3-羟基丙基]苯甲酸酯(1)出发。将Methyl 2-[(3S)-[3-[(2E)-(7-氯喹啉-2-基)乙烯基]苯基]-3-羟基丙基]苯甲酸酯(1)与亚磺酰氯或甲磺酰氯-溴化锂或三甲基氯硅烷-碘化钠在存在或不存在碱的条件下反应,可以得到Methyl 2-[(3S)-[3-[(2E)-(7-氯喹啉-2-基)乙烯基]苯基]-3-卤代丙基]苯甲酸酯。
