with manganese dioxide in toluene;

Steps:

2 C: 1-(2-Bromophenyl)isoquinoline

C: 1-(2-Bromophenyl)isoquinoline A mixture of 28.6 g (100 mmol) of 1-(2-bromophenyl)-3,4-dihydroisoquinoline, 86.9 g (1 mol) of manganese dioxide and 200 ml of 1,2-dichlorobenzene was stirred at 180° C. for 5 h. After cooling, the mixture was diluted with 500 ml of toluene and filtered through silica gel. After the solvent had been removed, the product was obtained as a yellow oil. The yield at a purity of approx. 99.0% was 26.0 g (91 mmol), 91.4% of theory. ¹H NMR (CDCl₃): [ppm]=8.63 (m, 1H), 7.86 (m, 1H), 7.73-7.61 (m, 4H), 7.51-7.42 (m, 3H), 7.37-7.33 (m, 1H).
