Reaction Steps

A mixture of potassium t-butoxide (0.34 g, 3.0 mmol) in 8 mL NMP stirred at room temperature was treated with a solution of ethyl 2-(3-fluoroisonicotinoyl)-4-methyl-3-oxopentanoate (0.28 g, 1.00 mmol) in 1 mL NMP drop wise. The dark red solution was stirred at room temperature for 15 hours, M+1=262. There were two spots that had the MS=262. The mixture was poured into 200 mL water. The mixture was extracted with DCM (3×50 mL). The combined organic layers were washed with brine (20 mL), dried, and concentrated. The crude product was purified by column eluting with 10-50% EtOAc/hexane to give 0.2 g oil. MS m/e: (M+H)+ 262.
