Reaction Steps

A mixture of 19.9 g. (0.1 mol.) of aminotrichloropyrazine, 25.2 g. (0.105 mol.) of sodium sulfide nonahydrate in 500 ml. of 2-propanol was heated to boiling under reflux for 5 hours. After cooling, the reaction mixture was filtered. The filtrate was neutralized with hydrochloric acid and filtered. The solid was washed with water and dried to give 11.4 g. (58% yield) of product.
