50℃で5時間撹拌した。溶媒を減圧下に留去した後、残渣にトルエン(15 ml)、酢酸エチル(15 ml)、水(15 ml)を加え、よく撹拌した。有機層を分離し、食塩水(20 mL)で洗浄後、無水硫酸マグネシウムで乾燥、ろ過した後、減圧下に濃縮してメントール(1.48 g, 9.5 mmol)を回収した。一方、水層は再度トルエン(10 ml)と酢酸エチル(10 ml)を加えて洗浄し、分離した水層にトルエン(20 ml)と酢酸エチル(20 ml)を加えて、激しく撹拌しながら0.3M HCl(60 ml)をゆっくりと注いで弱酸性にした。有機層を水(20 ml)で3回洗浄し、無水硫酸マグネシウムで乾燥、ろ過した後、減圧下に濃縮して式(3a)で示されるカルボン酸を淡黄色の液体として得た(3.26g, 85%)。
