Procedure
To a solution of 6.6 ml. (60 mmol) trichloromethanesulphenic acid chloride in 900 ml chloroform one adds dropwise at 0° C. a solution of 5.6 g (60 mmol) 2-aminopyridine and 8.3 ml triethylamine in 50 ml chloroform. One after-stirs for 10 min. and adds dropwise thereto a solution of 6.0 g (60 mmol) 2-aminothiazole and 25 ml triethylamine in 100 ml chloroform. After 3 h stirring at room temperature, one evapovates and washes the precipitate with methanol. There remain 8.9 g of title compound (63% of theory) of the m.p. 169°-171° C.
