Reaction Steps

A mixture of 1-[7-methyl-1-(2,4,6-trimethyl-phenyl)-1,4-dihydro-2H-pyrimido[4,5-d][1,3]oxazin-5-yl]-propan-1-ol (50 mg), methyl isocyanate (0.25 ml), dimethylaminopyridine (37 mg) in dichloromethane (2 ml) was heated at reflux for 1 hr. The mixture was quenched with water and extracted with chloroform. The organic layer was separated, dried and concentrated to give a clear oil (70 mg). The oil was purified by silica gel thin layer chromatography plate using 40% ethyl acetate in hexane as solvent to give 36 mg of the title compound.
