Reaction Steps

Imidazole (3.73 g) was added in one portion to a solution of 2-aminophenol (2.0 g) in dry dimethylformamide (10 ml) stirred at 25° C. under nitrogen. Chlorotrimethylsilane (2.98 g) was added dropwise over 5 minutes and stirring continued for a further 18 hours. The mixture was poured onto water (30 ml) and extracted with diethyl ether (2×60 ml). The organic solution was separated and washed with 2N sodium hydroxide (2×40 ml), brine and dried over magnesium sulphate. Evaporation of the filtrate under reduced pressure gave an oil. Column chromatography on silica eluting with 10% ether:hexane gave 2-trimethylsilyloxyaniline (0.85 g), NMR 1H: 0.2(9H,s), 3.5(2H,s), 6.4(4H,m).
