Reaction Steps

1-[6-(3-{4-Amino-6-[methyl(phenyl)amino]-1,3,5-triazin-2-yl}-1,2,4-oxadiazol-5-yl)pyridin-3-yl]ethan-1-one (Intermediate 141, 0.934 g, 2.40 mmol) was suspended in THF (60 mL), sodium borohydride (0.227 g, 6.01 mmol) was added and the mixture stirred at room temperature for 2 h. EtOAc (50 mL) and water (100 mL) were added and the organic layer separated. The aqueous layer was neutralised using 1M aq. hydrochloric acid and extracted with EtOAc (3×30 mL). The combined organic layers were dried over sodium sulfate and concentrated under vacuum to afford the title compound as a pale yellow solid (1.0 g), which was used in the next step without further purification. Method C HPLC-MS: MH+ requires m/z=391 Found: m/z=391, Rt=1.18 min (84%).
