Reaktionsschritte
The thus-obtained methyl 4,4-ethylenedioxy-1-methylcyclohexanecarboxylate (37.8 g) was dissolved in ether (100 ml), and the solution was added dropwise to a refluxing suspension of LiAlH4 (6.7 g) in ether (400 ml). After the addition, the mixture was stirred at room temperature for an hour and then cooled with ice. Ethyl acetate (20 ml) and then water (35 ml) were added dropwise cautiously thereto. The solid precipitate was filtered off, and the filtrate was distilled under reduced pressure to give 4,4-ethylenedioxy-1-methylcyclohexanemethanol (29.5 g, 89.9% yield, b.p. 120°-125° C./0.5 mmHg, m.p. 42°-43° C.).
