Yield:-
Reaction Conditions:
with triethylamine;triphenylphosphine in dichloromethane at 0 - 5; for 6 h;Product distribution / selectivity;
Steps:
2
(Z)-2-(5-amino-l,2,4-thiadiazole-3yl)methoxyiminoacetic acid (100 g) and 2,2'- dithio(bis)benzothiazole (214 g) were added at O0C to 50C to a solution of triphenylphosphine (168.6 g) in dichloromethane (600 ml). Triethylamine (76 ml) was added to the reaction mixture in 60 minutes duration at O0C to 50C and stirred for 5 hours at O0C to 50C. The reaction mixture was filtered through a centrifuge, washed with dicholoromethane (200 ml) and spun for 30 minutes to 60 minutes. The solid was air dried at 4O0C to 450C to obtain the title compound. Yield: 149 g
