合成路线1
该中间体在本合成路线中的序号：(VII)The condensation of 2-chloro-4-(piperidin-1-ylmethyl)pyridine (V) with 4-(tetrahydropyranyloxy)-2(Z)-buten-1-ol (VI) by means of NaH in THF gives 4-(piperidin-1-ylmethyl)-2-[4-(tetrahydropyranyloxy)-2(Z)-butenyloxy)pyridine (VII), which is deprotected with 4-methylbenzenesulfonic acid in methanol, yielding the free butenol (VIII). The acylation of (VIII) with methanesulfonyl chloride in toluene affords the corresponding mesylate (IX), which is finally condensed with 2-(2-furylmethylsulfonyl)acetamide (X) (obtained from the corresponding 4-nitrophenyl ester (XI) with ammonia) by means of potassium tert-butoxide in toluene.
