Reaction Steps

Under N2, methyl 2-cyano-6-methylisonicotinate (0.490 g, 2.78 mmol, Eq: 1.00) was dissolved in Tetrahydrofuran (25 ml) and Methanol (3.03 ml). At 0° C., 1M LiOH in H2O (3.48 ml, 3.48 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. Pink solid. MS (EIC): 160.8 ([M+H]+)
