Reaction Steps

To a stirred solution of 2.0 g (13 mmol) of 5,6,7,8-tetrahydroquinolin-8-ol and 3.3 g (27 mmol) of 4-(dimethylamino)pyridine in 30 mL of dichloromethane was added 1.3 mL (16 mmol) of methanesulfonyl chloride under an atmosphere of nitrogen. The reaction mixture was stirred for 8 h and then diluted with 30 mL water. The aqueous phase was then extracted with dichloromethane (3×30 mL) and the combined organics were dried over magnesium sulfate, filtered and evaporated in vacuo to afford the title compound as a light orange gum that was used without further purification. LC/MS: m/z (ES) 172.0 (MH)+.
