Participants

Reaction Conditions

Reaction Steps

To a cold solution of acetonitrile (2 mL, 38 mmol, 2.8 eq) in THF (30 mL) at −72° C. (Dry-ice/IPA) was added dropwise nBuLi (12 mL, 30 mmol, 2.2 eq) under argon atmosphere. The reaction mixture became an orange suspension after 1 h. A solution of methyl 2-{[(1E)-(dimethylamino)methylidene]amino}-5-(methyloxy)benzoate (3.2 g, 13.6 mmol, 1 eq) in THF (30 mL) was then added dropwise while the internal temperature was maintained at −72° C. The resulting mixture was slowly warmed to RT overnight. To the resulting light-brown suspension was added glacial acetic acid (6 mL) with slight cooling. After stirring for 1 h, the suspension was then quenched with water (60 mL) and filtered to give the titled compound (2.3 g, 85% yield).
