Reaction Steps

Under N2, methyl 2-cyano-6-methoxyisonicotinate (0.433 g, 2.25 mmol, Eq: 1.00) was dissolved in THF (25.0 ml) and Methanol (3.03 ml). At 0° C., 1M LiOH in H2O (2.82 ml, 2.82 mmol, Eq: 1.25) was added and the RM was stirred at 0° C. for 30 minutes. Control with TLC: the reaction was finished. The reaction mixture was acidified with 1M HCl. The mixture was diluted with H2O and extracted with EtOAc. The organic phase was dried over MgSO4; filtered; concentrated in vacuo. Light yellow solid. MS (EIC): 176.8 ([M−H]−)
