실험 절차
A mixture of 2.5 g. (16.8 mmol) 7-amino-1,2,3,4-tetrahydroisoquinoline, 30 ml. ethyl acetate and 2 ml. isopropenyl acetate was refluxed for approximately 16 hours and was then concentrated to dryness at reduced pressure. The residue was then recrystallized from a mixture of ethyl acetate and petroleum ether to afford 2-acetyl-7-amino-1,2,3,4-tetrahydroisoquinoline with a melting point of 98°-100° C.
