Lithium diisopropylamide → HCID 59706204, compound

Participants

Reaction Steps

A solution of bis-(3-pyridyl)methane (61 mg) in 3 mL THF was cooled to 0 C, and LDA (1.5 M in cyclohexane, 0.240 mL) was added dropwise via syringe. After the mixture had been stirred for 30 min, a solution of 2-[methyl(pyridin-3-yl)amino]nicotinaldehyde (73 mg) in 3 mL THF was added dropwise over 30 min. After 3 h stirring at 0 C, the reaction was quenched with water, then partitioned between saturated aqueous sodium bicarbonate and CH2Cl2. The aqueous solution was extracted with CH2Cl2 (2×), and the combined organic solutions were dried (Na2SO4) and purified by reverse phase HPLC to give 40 mg of 1-{2-[methyl(pyridin-3-yl)amino]pyridin-3-yl}-2,2-dipyridin-3-ylethanol.
