실험 절차

3-Methylbut-2-en-oylchloride (24.2 g) was added dropwise to a stirred solution of 2-methylaniline (20 g) in anhydrous pyridine (200 cm3) cooled to 0°. After 1 hour solvent was evaporated in vacuo to yield a solid which was recrystallised from ether/petroleum ether (boiling range 40-60) to afford the title compound, m.p. 105 (29.5 g).
