YieldReaction ConditionsOperation in experiment
4% With hydrogenchloride; triethylamine; In N-methyl-acetamide; chloroform; water; mineral oil; benzene; PREPARATION 11 5-Methoxy-2-[(1-methyl-3-pyrrolidinyl)oxy]benzamide To a solution of 151 g (1.5 mole) <strong>[13220-33-2]1-methyl-3-pyrrolidinol</strong> and 166 g (1.6 mole) triethylamine in 1500 ml of dry benzene was added dropwise 171 g (1.5 mole) of methanesulfonyl chloride with cooling. The reaction mixture was stirred at room temperature for one hour and filtered. The filtrate was concentrated under reduced pressure to give an orange-colored oil. In another vessel, to a suspension of 50percent sodium hydride/mineral oil (72 g; 1.5 mole) in 150 ml dimethylformamide the sulfonate prepared above and 139 g (0.93 mole) of 5-methoxy salicylamide dissolved in 600 ml dimethylformamide were added dropwise with cooling. The reaction mixture was heated at reflux for 14 hr. After cooling, the reaction was diluted with 1000 ml of water and extracted three times with 700 ml portions of chloroform. The combined chloroform extracts were washed thrice with water and extracted thrice with 500 ml portions of 3N hydrochloric acid. The aqueous layer was made alkaline and extracted with chloroform. The chloroform extracts were washed thrice with water, dried over magnesium sulfate and evaporated under reduced pressure to give a viscous brown oil. Vacuum distillation of this material yielded a viscous orange oil which was dissolved in chloroform, extracted in acid; made alkaline and extracted into chloroform again. Evaporation of the solvent gave a dark brown oil which solidified under reduced pressure. Three recrystallizations from ethyl acetate gave 10 g of white crystals (4percent), m.p. 85°-87° C. Analysis: Calculated for C13 H18 N2 O3: C, 62.38; H, 7.25; N, 11.19. Found: C, 62.47; H, 7.26; N, 11.20.
