실험 절차

A mixture of 6-[[5-Fluoro-2-(3,4,5-trimethoxyanilino)pyrimidin-4-yl]amino]-2,2-dimethyl-4H-pyrido[3,2-b][1,4]oxazin-3-one (Step B) (382 kg, 1.00 mol eq), tetra-n-butylammonium chloride (57.5 kg, 0.25 mol eq) and potassium carbonate (252 kg, 2.25 mol eq) in N,N-dimethylacetamide (1792 kg) is warmed to about 40° C. with stirring. To this is added a solution of ditert-butyl chloromethyl phosphate (Example 2) in isopropyl acetate (229 kg ditert-butyl chloromethyl phosphate, 1.10 mol eq, about 25% w/v solution). The resulting mixture is stirred for about 8 hours and then cooled to about 5° C. Isopropyl acetate (1329 kg) is added and then water (2292 kg) slowly, maintaining the temperature at <25° C. The layers are then separated, retaining the upper layer of the three observed. To this is added acetic acid (99 kg) and the resulting solution of the sub-title compound is used directly in the next step.
