반응 단계

In a similar manner 58 g of 1-ethyl-2-aminomethylpyrrolidine was reacted with 131 g of 7-ethylsulfonyl-1,4-benzodioxane-5-carbonyl chloride to give, after treatment and purification, 103.5 g of N-(1-ethyl-2-pyrrolidylmethyl)-7-ethylsulfonyl-1,4-benzodioxane-5-carboxamide (M.P.: 118°-119° C.; yield: 60.2%). 100 g of the base produced was dissolved in 220 ml of acetone and then the solution was filtered on carbon black and a solution of 9.5 g of hydrochloric acid in acetone was added. The resulting hydrochloride crystals were dried off, washed with acetone and then dried. 96 g of N-(1-ethyl-2-pyrrolidylmethyl)-7-ethylsulfonyl-1,4-benzodioxane-5-carboxamide hydrochloride was produced (M.P.: 148°-150° C.; yield: 88.2%).
