Reaction Steps

A suspension of tert-butyl(1-(4-(7-phenyl-2-thioxo-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazin-6-yl)phenyl)cyclobutyl)carbamate (150 mg, 0.308 mmol) and cyclopropanecarbohydrazide (41 mg, 0.410 mmol) in p-xylene (1.5 ml) was heated to 150° C. for 20 minutes under microwave irradiation. The resulting reaction mixture was concentrated to dryness under reduced pressure and purified by Biotage silica gel chromatography (gradient 0% to 20% ethyl acetate in n-hexanes) to give the title compound (36 mg, 32%). LCMS (Method D): RT=1.457 min, M+1=536.
