実験手順
Analogous to the procedure described in Ex. 40, 6-fluoro-7-(methylamino)-2,3-dihydrobenzo[e][1,3]oxazin-4-one (0.100 g, 0.51 mmol) and 5-iodo-3-methylpyridin-2-amine (0.119 g, 0.53 mmol) were coupled to yield pure 3-(6-aminopyridin-3-yl)-6-fluoro-7-(methylamino)-2,3-dihydrobenzo[e][1,3]oxazin-4-one (0.020 g, 13%) after reverse phase HPLC purification. ES-MS (M+H)+=303.
