실험 절차

To a suspension of NaH (60%, 951 mg) in THF (dry) (40 mL) was added 2-chloroethanesulfonyl chloride (1.50 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature. A solution of 3-(6-methoxynaphthalen-2-yl)pyridin-2-amine (1190 mg) in THF (dry) (25 mL) was added at 0° C. and the mixture was stirred at room temperature overnight. The mixture was quenched with water. Water and EtOAc were added and the precipitates were collected, washed with water/EtOAc, dried in vacuo to give the title compound (835.3 mg). A part of this was recrystallized from MeCN-THF/IPE.
