Reaction Steps

Two grams of 2,6-dimethoxybenzoyl chloride dissolved in about 3 ml dichloromethane was added dropwise to a stirring solution of 1.99 g of 2-amino-5-(1-ethyl-1-methylpropyl)-6H-1,3,4-thiadiazine in 10 ml of pyridine. The mixture was stirred at room temperature for approximately 72 hours and poured into water. The product was extracted into ether and washed with water. The ether phase was dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The resulting oil was chromatographed over silica gel eluting with a 1:4 (v:v) mixture of ethyl acetate/toluene. Fractions containing the major component were combined and the solvent was evaporated therefrom to afford 0.15 g of N-[5-(1-ethyl-1-methylpropyl)-6H-1,3,4-thiadiazin-2-yl]-2,6-dimethoxybenzamide. mp=134°-140° C.
