Procedure

To a suspension of NaH (60%, 20.4 g) in THF (dry) (250 mL) was added 2-chloroethanesulfonyl chloride (32.2 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(4-phenoxyphenyl)pyridin-2-amine (29.09 g) in THF (dry) (150 mL) was dropwised at 0° C. and the mixture was stirred at room temperature under N2 for 2 days. The mixture was quenched with THF/water (v/v=5/1) at 0° C. under N2 carefully. Water (500 mL) and EtOAc (400 mL) were added to form precipitates (stirred for 30 min) which were washed with water and EtOAc, collected and crystallized from DMSO/EtOH (500 mL/1000 ml, at 90° C.) to give the title compound (36.0 g) as colorless crystals.
