実験手順

N-(2,4-Difluorophenyl)-1-ethyl-5-(2-methyl-4,5-dihydro-1,3-dioxol-2-yl)oxindol-3-carboxamide (636 mg., 1.58 mmoles) was dissolved in 15 ml. of tetrahydrofuran to which was added 10 ml. of 1N hydrochloric acid. The solution was stirred for one hour followed by the addition of an equal volume of water. The resulting precipitate was filtered, vacuum dried and recrystallized from diisopropyl ether - methylene chloride, 412 mg. (73% yield), m.p. 160°-161° C.
