To a solution of 1.71 g of 2-amino-5-(1,1-dimethylethyl)-6H-1,3,4-thiadiazine and 1.01 g triethylamine in 18 ml dioxane was added 2.11 g of 2,6-dimethoxybenzoyl chloride. The reaction mixture was stirred at room temperature for 3 hours and poured into 100 ml water. The solid was collected and recrystallized from ethanol. The second crop of material provided 0.43 g of N-[5-(1,1-dimethylethyl)-6H-1,3,4-thiadiazin-2-yl]-2,6-dimethoxybenzamide. mp=175°-177° C.
