반응 단계

A mixture of 4-acetylamino-5-(3-methoxyphenyl)valeric acid (151 mg) and (+)-cinchonine (110 mg) in 1,4-dioxane (2.6 ml) was refluxed and the solution was allowed to cool. The resulting precipitates were collected by filtration and dried to give a salt of (S)-4-acetylamino-5-(3-methoxyphenyl)valeric acid and (+)-cinchonin (117 mg). This compound was recrystallized from 1,4-dioxane to give the pure salt (61 mg).
