実験手順: A mixture of 2.00 g (10.9 mmol) 1-allyloxy-4-chloromethyl-benzene and 917 mg (12.1 mmol) thiourea in 3.0 ml ethanol was heated to reflux for 7 h. Solvents were distilled off and the crystalline residue was washed with cold ethanol and isolated by filtration. After addition of 2.5 ml ethanol, 1.0 ml water and 0.7 ml 25% aqueous ammonia, the mixture was heated to reflux for 1 h. Ethanol was distilled off, then acidified with 0.5 ml half conc. HCl and extracted with ethyl acetate. The solution was dried over MgSO4 and solvents were removed in vacuo to yield 1.59 g (81%) colorless oil, which was used immediately. was heated to reflux for 7 h Solvents were distilled off the crystalline residue was washed with cold ethanol isolated by filtration the mixture was heated to reflux for 1 h Ethanol was distilled off extracted with ethyl acetate The solution was dried over MgSO4 and solvents were removed in vacuo

実験手順: 197 mg 8.21 mmol) 95% sodium hydride were given at −50° C. to a solution of 1.00 g (5.47 mmol) 1-allyloxy-4-chloromethyl-benzene and 619 mg (5.47 mmol) 2-(1H-[1,2,3]-triazol-1-yl)-ethanol in 9.0 ml DMF. The mixture was allowed to warm slowly to r.t., stirred overnight and 10 ml water added. The formed oil was collected with 10 ml dichloromethane, the aqueous phase extracted with 10 ml dichloromethane and the combined organic phases dried over Na2SO4. The formed oil was collected with 10 ml dichloromethane the aqueous phase extracted with 10 ml dichloromethane the combined organic phases dried over Na2SO4

実験手順: 7.67 g (67.0 mmol) methanesulfonyl chloride were given at 0° C. to a solution of 10.0 g (60.9 mmol) (4-allyloxy-phenyl)-methanol and 9.34 ml (67.0 mmol) triethylamine in 35 ml dichloromethane and stirred at r.t. overnight. The mixture was poured in ice water, extracted with dichloromethane and the organic phase dried over Na2SO4. After removal of solvents the residue was purified by chromatography on silica gel (ethyl acetate/n-heptane 1:5) to yield 3.12 g (28%) pale yellow oil. extracted with dichloromethane the organic phase dried over Na2SO4 After removal of solvents the residue was purified by chromatography on silica gel (ethyl acetate/n-heptane 1:5) to yield 3.12 g (28%)
