Reaction Steps
A mixture of 2-(4-nitrophenoxy)isobutyric acid (50) (5 g), isobutyl chloroformate (4.36 mL) and triethylamine (8 mL) in dichloromethane (20 mL) was stirred at room temperature for 1 hour. Then 2.0 M ammonia in methanol (20 mL) was added to the solution. The resulting solution was stirred at room temperature for 2 hours and then solvent was removed under reduced pressure. The mixture was purified by recrystallization from EtOAc and hexanes to give 2-(4-nitrophenoxy)-2-methylpropanamide (51).
