실험 절차

To 3,4-dihydro-2H-naphthalen-1-one oxime (5 g, 31 mmol), PPA (50 g) was added and the mixture was heated at 120° C. for 4.5 hrs. While hot the mixture was quenced in a slurry of ice and water and vigorously stirred until a precipitate formed. The precipitate was filtered and rinsed with water to yield 1,3,4,5-tetrahydrobenzo[b]azepin-2-one (3.1 g). MS [M+H]+: 162.0; tR=1.76 min. (method 1)
