Participants

Reaction Steps

A solution of diazomethane in diethyl ether was added to a solution of Compound 113 (0.70 g) in tetrahydrofuran (5 ml) at room temperature until the starting material disappeared. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 6-methoxycarbonyl-2,2-dimethyl-4-(2-pyridyl)-2H-1,3-benzoxazine (0.49 g) (Compound 6).
