1-(2-Diethylaminoethyl)-4-trifluoromethyl-6-iodo-3-hydroxy-3-(2-chlorophenyl)oxindole → 1-(2-Diethylaminoethyl)-4-trifluoromethyl-6-(4-morpholinocarbonyl-1-butynyl)-3-hydroxy-3-(2-chlorophenyl)oxindole

Participants

Reaction Steps

The title compound (246 mg) was prepared from (+)-1-(2-diethylaminoethyl)-4-trifluoromethyl-6-iodo-3-hydroxy-3-(2-chlorophenyl)oxindole (300 mg, 0.543 mmol) and 4-morpholinocarbonyl-1-butyne by the procedure similar to that described in Reference Example 21. The hydrochloride of the title compound was obtained by treating with 4 N HCl in dioxane followed by concentration to dryness. The NMR spectra of the title compound exhibited the same as in Example 70. [α]D +58.3° (c=0.252, MeOH).
