Procedure
A solution of 479.2 mL (0.958 mole) methylamine (2M in tetrahydrofuran) was added dropwise to 99.44 gm ethyl crotonate with stirring. After stirring 5 days at room temperature the reaction mixture was concentrated under reduced pressure to remove tetrahydrofuran. The residue was distilled to provide 91.25 gm (72%) of the desired product in 2 fractions. MS(FD): m/e=145 (M+); EA: Calculated for: C7H15NO2: Theory: C, 57.90; H, 10.41; N, 9.65. Found: C, 57.61; H, 10.66; N, 9.88.
