Lithium Hydroxide → 4-(5-Nitropyridin-2-yl)butanenitrile

Participants

Reaction Steps

To a solution of compound 76 (3.3 g, 10.7 mmol) in CH3OH (100 mL) was added a solution of LiOH (15.4 g, 64.2 mmol) in H2O (100 mL) at room temperature with stirring. The mixture was stirred at room temperature for 2 h. Methanol was removed in vacuo and the residual aqueous solution was washed with EtOAc (two times), then was acidified to pH=2 with 1N HCl. The aqueous phase was extracted with EtOAc. The combined organic extract was dried over Na2SO4, then was stirred at 50° C. for overnight. The solution was concentrated to afford compound 77 (1.9 g, 95%) as a yellow oil.
