68% | EXAMPLE 51 5-Dimethylamino-N-(4-bromo-3-methyl-5-isoxazolyl)-1 -naphthalenesulfonamide 5-Dimethylamino-N-(4-bromo-3-methyl-5-isoxazolyl)-1-naphthalenesulfonamide was prepared from <strong>[33084-49-0]5-amino-4-bromo-3-methylisoxazole</strong> and 5-dimethylaminonaphthalenesulfonyl chloride according to the procedures described in Example 5. The crude product was purified by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 87-89 C., yield 68%. |
Yield | Reaction Conditions | Operation in experiment |
---|---|---|
86.1% | With triethylamine; In tetrahydrofuran; | EXAMPLE 11 Naphthalenesulfonamide, 5-(dimethylamino)-N-(2-bromoethyl) A suspension of 5-dimethylaminonaphthalene-1-sulfonyl chloride (50.0 g, 0.185 mol) and 2-bromoethylamine hydro-bromide (40.4 g, 0.197 mol) in THF (500 mL) was cooled to 2 C. A solution of triethylamine (38.5 g, 0.380 mol) in THF (250 mL) was added dropwise over a 2 h period while maintaining the internal temperature below 6 C. After complete addition the mixture was stirred at ambient temperature for 17 h. The mixture was clarified then concentrated to an orange oil which was chromatographed over silica (2.2 kg) packed and eluted with hexanes-EtOAc (3:1). Fractions (500 mL) containing the purified product were combined, clarified, then concentrated to a damp solid. This material was triturated in hexanes (250 mL), collected on a filter, washed with hexanes (50 mL) then dried to constant weight in vacuo at 40 C. to give 56.9 g (86.1% yield) of product as a off-white crystalline solid. |
