Reaction Steps

A solution of N-[4-(5-chloro-2-methyl-phenyl)-pyridin-3-yl]-2,2-dimethyl-propionamide (1 g, 3.3 mmol) in 3M aqueous HCl (50 mL) was stirred at 90° C. for 18 hours. The reaction mixture was poured on 200 mL 1M aqueous NaOH solution and 150 mL EtOAc. The layers were separated and the aqueous layer was extracted a second time with 150 mL EtOAc. The combined organic layers were washed with 150 mL brine, dried over MgSO4, filtered and concentrated under vacuum. Light brown viscous oil (720 mg, 99%). MS (ESI): m/z=219.068 [M+H]+.
