Reaktionsschritte
A solution of 2-ethoxycarbonylimino-3-(3-trifluoromethylphenyl)-5-bromothiazoline (4.7 g), tributyltin hydride (6.9 g) and a catalytic amount of benzoyl peroxide in tetrahydrofuran (100 ml) was refluxed for 10 hours. The solvent was removed by distillation, and the residue was washed with hexane. Recrystallization from a mixture of hexane and ethanol gave 2.85 g of 2-ethoxycarbonylimino-3-(3-trifluoromethylphenyl)thiazoline (Compound (xii)).
