Reaction Steps
To a solution of 4-pivaloylaminopyridine (7.0 g, 39 mmol) in tetrahydrofuran (100 ml) was added n-butyllithium (39.3 ml, 98 mmol, 2.5 M solution in tetrahydrofuran) at −78 ° C. under a N2 atmosphere. The reaction mixture was stirred at 0° C. for 5 h, re-cooled to −78 ° C. and quenched with a solution of N-methoxy-N-methyl-4-fluorobenzamide (7.9 g, 43 mmol) in 100 ml tetrahydrofuran. The reaction mixture was warmed to room temperature and poured into water. The product was extracted into ethyl acetate. The organic layers were washed with brine, dried over sodium sulfate and evaporated to dryness. The residue was purified by flash chromatography (10% ethyl acetate/hexanes gradient) to afford N-[3-(4-fluorobenzoyl)-pyridin-4-yl]-2,2-dimethylpropanamide (10 g).
