Sodium Hydroxide → HCID 57635952, compound

Participants

Reaction Steps

To a solution compound (9a) (0.12 g, 0.3 mmol) in 10 mL of MeOH and 0.5 mL of H2O was added NaOH (40 mg, 1 mmol). The reaction mixture was refluxed for 1 h, concentrated to re-move MeOH. The reaction solution was adjusted to pH 4 with HCl and the solid was collected by filtration, washed with water, and dried in vacuum over P2O5 to give 5-[2-(3-amino-phenylamino)-4-cyclopropylamino-pyrazolo[1,5-a][1,3,5]triazin-8-yl]-pentanoic acid (10a) (0.1 g, 90%).
