実験手順: 15 parts of 2-methyl-3-(4-bromophenyl)-propyl chloride and 28 parts of cis-2,6-dimethylmorpholine were stirred at 150° C. for 8 hours. The reaction mixture was cooled, poured into 100 parts of water, brought to pH 9-10 with saturated aqueous Na2CO3 solution and extracted with methylene chloride. The organic phase was dried and concentrated and the residue was distilled to give, at a boiling point of 100°-102° C./0.01 mbar, 15.8 parts of 4-[3-(4-bromophenyl)-2-methylpropyl]-cis-2,6-dimethylmorpholine of nD22 1.5265. The reaction mixture was cooled extracted with methylene chloride The organic phase was dried concentrated the residue was distilled

実験手順: a solution of 24.7 parts of 2-methyl-3-(4-bromophenyl)-propyl chloride in 20 parts of tetrahydrofuran (THF) were added dropwise to 2.4 parts of magnesium in 25 parts of THF. The reaction was maintained at from 50° to 52° C., and the mixture was then refluxed for a further 30 minutes. 16.5 parts of triethylchlorosilane were added dropwise at room temperature and the mixture was then refluxed again for 6 hours, cooled and filtered. The solution was concentrated and the residue was distilled to give, at a boiling point of 115°-120° C./0.01 mm Hg, 20.3 parts of 2-methyl-3-(4-triethylsilylphenyl)-propyl chloride of n24 1.5080. The reaction was maintained at from 50° to 52° C. the mixture was then refluxed for a further 30 minutes the mixture was then refluxed again for 6 hours cooled filtered The solution was concentrated the residue was distilled
