Reaction Steps

2-(2-(1-Methyl-3-(pyridin-4-yl)-1H-1,2,4-triazol-5-yl)ethyl)isoindoline-1,3-dione (114.9 mg, 345 μmol) was dissolved in methylamine solution in EtOH (3.07 mL, 22.5 mmol) and stirred at RT for 1 h. The reaction mixture was evaporated to give light brown solid. The solid was again dissolved in methylamine solution in EtOH (3.07 mL, 22.5 mmol) and the mixture was heated to 50° C. and stirred for 3 h. All volatiles were removed in vacuo and the residue was suspended in dichloromethane (1.5 mL) and filtered. The filtrate was evaporated to give the product as light yellow solid (81.3 mg (80% purity), 256 μmol, 74.2%) which was used without purification for the next step. MS: M=204.2 (M+H)+
