13.59 g of the tris(2,4-bis(N,N-bis(2-t-butyldimethylsilyloxyethyl)sulfamoyl)phenyl)bismuthine preparation prepared in Example 5 was dissolved in a mixed solvent containing 13.6 ml of ethanol and 27 ml of dichloromethane, and 0.272 g of p-toluenesulfonic acid monohydrate was added thereto. The mixture was refluxed under heating at 50° C. for 6 hours, and then cooled to room temperature. The crystals were collected by filtration, washed with 29.5 ml of dichloromethane and dried. As a result, 5.54 g of the title compound was obtained as crystals with a melting point of 110°-113° C.
