実験手順
81 ml of triethylamine was gradually added to a dimethylformamide solution containing 136 g of 5-bromosalicylhydroxamic acid prepared as in (2-2) above and 54 ml of N,N-dimethylcarbamyl chloride at room temperature (about 20°-30° C.), then stirred for 10 hours. This solution was poured into ice-water to collect the precipitate by filtration followed by drying. Yield: 102 g; mp. 118°-119° C. (dec.)
