Reaction Steps

A mixture of 2-[2-(1-tert-butoxycarbonylpiperidin-4-yl-oxy)-4-tert-butylphenyl]-4H-pyrido[3,4-d][1,3]oxazin-4-one (100 mg, 0.21 mmol), KCN (100 mg), 5-chloro-2-aminopyridine (53 mg, 0.42 mmol), and dry DMF (2 mL) was heated at 70° C. for 4 h, then quenched with brine (25 mL). The mixture was extracted with 10% MQOH in EtOAc (2×20 mL), and the combined extracts were washed with brine (3×100 mL) then dried over MgSO4. After filtering, the filtrate was concentrated to an oil which was purified by chromatography using 60% EtOAc in hexanes to give 30 mg of an oil which crystallized.
