Procedure
Into a 200 ml round bottom flask 50 ml of methanol, 30.0 g of 2-cyclohexylpropanal, 36.1 g of methyl orthoformate, and 0.5 g of ammoniumchloride were charged and the mixture was stirred at room temperature for 12 hours. After washing the resulting reaction mixture with water, the residue was distilled to prepare 37.5 g of Compound No. 4 (purity: 99.3%, boiling point: 83° C./5 mmHg). The compound was a colorless, transparent liquid having a floral and fruity odor.
