반응 조건

온도: -20 °C

실험 절차

The mixture is cooled to -20° C. and the methyl ester (VII) (30 g; 0.134 mole) is added dropwise, at the end of which a saturated ammonium chloride solution is added slowly. The phases are separated, the organic phase is washed to neutrality yielding a pale yellow oil (40.7 g; yield=98%).
