General procedure: To a stirred solution of 2-chloro-4-oxo-4H-pyrido [1,2-a]pyrimidine-3-carbaldehyde (100mg, 0.479mmol) in THF (3mL) was added benzylamine (0.058mL, 0.527mmol) and TEA (0.1mL, 0.719mmol). The reaction mixture was stirred at 70C for 3h. after the mixture was concentrated, 1N aqueous HCl solution in THF (1/3 ratio, 4mL). The reaction mixture was stirred at 70C for 1h. after reaction was completed, the mixture was evaporated and neutralized to approximately pH 7 by adding 1N NaOH. The pale solid was collected by filtration and washed with H2O to give 5a (117mg, 87%) as a brown solid. |
