Reaction Steps
To a solution of 12.6 g of 1-bromo-3,3-dimethyl-2-methylcarbamyloximinobutane in 100 ml of anhydrous ether is added, dropwise, 7.8 g (0.11 mol) of pyrrolidine. The mixture is stirred at room temperature for 1 hour and at reflux for 0.5 hour, then cooled and washed with water. The ether solution is separated, dried, and stripped of solvent to give 11.8 g of amber oil which solidifies on standing to an amber solid, m. 43°-46° C. Properties of this and analogous compounds prepared by substantially the same procedure are shown in Table 3.
