Reaction Steps

Oxone (14 g, 23 mmol) was added to a solution of 1-[3-(N,N-dimethylamino)propylthio]-4-bromobenzene (Method 67; 5.24 g, 19.1 mmol) in MeOH (150 ml) and water (30 ml) and the mixture was stirred at ambient temperature for 90 minutes. The reaction mixture was poured onto an Isolute SCX-2 column, washed MeOH (6×40 ml) and the product eluted with 2% methanolic ammonia (10×40 ml). The solvent was evaporated and residue purified by flash chromatography on silica gel eluting with DCM/2% methanolic ammonia (100:0 increasing in polarity to 94:6) to yield the title compound (4.68 g, 80%) as a pale yellow oil. NMR 1.62 (m, 2H), 2.03 (s, 6H), 2.19 (t, 2H), 3.32 (m, 2H), 7.81 (m, 4H); m/z 306.
