Reaction Steps

Diisopropylamine (0.93 ml; 6.55 mmol) in THF (6 ml) is cooled to −78 C and treated with nBuLi (3.8 ml; 6.08 mmol of a 1.6 M solution hexane). 2-Fluoro-4-methylpyridine (620 mg, 5.4 mmol) is added dropwise and stirred under argon for 30 min. 4-Fluoro-N-methoxy-N-methylbenzamide (1 g, 5.46 mmol) is added dropwise in THF (0.5 ml) and the reaction mixture allowed to warm up to room temperature within 10 min. then poured on a saturated solution of NaCl and extracted with TBME three times. The combined organic phases are washed with water, dried over Na2SO4, filtered and evaporated to dryness to yield the title compound as pale yellow crystals. Purification by recrystallisation from hot TBME rendered the desired compound as white solid (630 mg; 50%).
