Reaction Steps

A mixture of 4-(2,3-dihydro-6-methyl-4-oxo-5-phenyl-4H-1,3-oxazin-3-yl)-4-methylpent-1-en-3-one (50 mg), 3-phenoxyaniline (30 mg) and pyridine (0.2 ml) was heated at 40° C. for 1 hour then stirred overnight at 20° C. and at 40° C. for 4 hours. After evaporation the residue was purified by silica gel column chromatography eluting with isohexane/ethyl acetate to give 5-(3-phenoxyphenyl)amino-2-(2,3-dihydro-6-methyl-4-oxo-5-phenyl-4H-1,3-oxazin-3-yl)-2-methylpentan-3-one (Compound 1082, 69 mg), NMR 1.4(s,6H), 1.9(s,3H), 2.8(m,2H), 3.4(m,2H), 5.3(s,2H), 6.3-6.4(m,3H), 6.9-7.4(m,11H).
