Reaction Steps

tert-Butyl 3-amino-6-(1-methyl-1H-pyrazol-4-yl)-2-(quinolin-6-ylmethylamino)pyridin-4-ylcarbamate (890 mg, 2 mmol) was added to a solution of acetic acid (5 mL) and water (5 mL) at 0° C., followed by the addition of NaNO2 (300 mg, 4 mmol) in H2O (0.5 mL). The reaction was stirred at 0° C. for 1 h, then basified with 30% NaOH to pH=8. The resulting mixture was filtered to afford a solid. The solid was treated with TFA (3 mL), and then stirred at room temperature for another 0.5 h, before treated with aqueous Na2CO3 to adjust the pH to 8. The resulting mixture was purified by chromatography to afford the title compound (190 mg). MS: 358 (M+1)+.
