実験手順
A mixture of 15.0 g of 10-hydroxy-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-4-one, 150 ml of epichlorohydrin and 0.7 ml of piperidine is heated to the boil for 30 minutes. After concentration by evaporation at reduced pressure, the mixture is dried at 40°, whereupon a mixture of 10-(2,3-epoxypropoxy)-4H-benzo[4,5]-cyclohepta[1,2-b]thiophen-4-one and 10-(3-chloro-2-hydroxypropoxy)-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-4-one is obtained, which is used further as such.
