Reaction Steps
To a 40-mL vial with magnetic stir bar at 25° C. was added the Ethylamine solution (0.91 g, 20 mmol, 1.3 mL, 70% w/v in water, 4.5 eq.) and methanol (5 mL). The reaction vial was cooled to 0° C. The Nosyl chloride (1.0 g, 4.5 mmol, 1 eq.) was added portion-wise keeping the temperature between 0-5° C. and stirring continued ×15 min. after addition was complete. Water (10 mL) was then added. A precipitate began to form immediately. Stirring was continued at 0° C.×30 minutes. The material was collected by filtration, rinsed with water, and dried thoroughly in vacuo to afford 827 mg (79% yield). LCMS (ESI) 231 (M+H); 229 (M−H).
