実験手順

To a suspension of NaH (60%, 42.0 g) in THF (dry) (350 mL) was added 2-chloroethanesulfonyl chloride (44.5 mL) at 0° C. and the mixture was stirred for 10 min at the same temperature. A solution of 3-(4-((tert-butyl(dimethyl)silyl)oxy)phenyl)pyridin-2-amine (78.8 g) in THF (dry) (350 mL) was added at 0° C. and the mixture was stirred at room temperature under N2 overnight. The mixture was quenched with water at 0° C. carefully. Additional water was added to form precipitates which were washed with water and EtOAc and collected to give the title compound (65.5 g) as an off-white solid.
