Versuchsvorschrift
4-Methyl 1-(3-methoxy-2-propen-1-yl)benzene was similarly prepared as described in Examples I and II. First, 4-methyl benzaldehyde (140 g, commercially available from Mitsubishi Gas Chemical Company, Inc.) was used to obtain 3-(4-methyl-phenyl)-propionaldehyde (130 g) with a boiling point of 120° C. at a pressure of 21 mmHg. 3-(4-Methyl-phenyl)-propionaldehyde (225 g) was consequently used to provide 4-methyl 1-(3-methoxy-2-propen-1-yl)benzene (139 g) with a boiling point of 117° C. at a pressure of 35 mmHg
