1-Ethyl-6-mercapto-3,4-dihydroquinolin-2(1H)-one → (2S,4R)-4-[3-(1-ethyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-ylthio)phenyl]-4-hydroxy-2-methyltetrahydropyran

Participants

Reaction Steps

Using an analogous procedure to that described in Example 6, 1-ethyl-6-mercapto-1,2,3,4-tetrahydroquinolin-2-one was reacted with (2S,4R)-4-hydroxy-4-(3-iodophenyl)-2-methyltetrahydropyran to give (2S,4R)-4-[3-(1-ethyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-ylthio)phenyl]-4-hydroxy-2-methyltetrahydropyran in 55% yield, m.p. 148°-149° C. (recrystallised from diethyl ether);
