Reaction Steps
To a solution of imidazo[1,2-a]pyridine-6-carbonitrile (7-1) (1.43 g, 10 mmol) in 3 mL of acetic acid were added sodium acetate (3.03 g, 37 mmol) and then formaldehyde (6 mL, 37% in water). The reaction mixture was stirred at 100° C. overnight. After cooled to room temperature, the mixture was adjusted to pH>7 with aqueous Na2CO3. The precipitate was collected to afford the title compound (1.4 g). MS (m/z): 174.0 (M+H)+
