الإجراء التجريبي
A solution of 49.8 g of 2,3-dihydro-2,2-dimethyl-6-(2-oxopropoxy)-4H-1,3-benzoxazin-4-one and 21.4 g of benzylamine in 700 ml of methanol is hydrogenated with the addition of 0.5 g of concentrated sulphuric acid and 3 g of Pt/C-catalyst (5%) until the equivalent amount of hydrogen has been asborbed. Working up analogously to Example (1d) yields 6-(2-benzylaminopropoxy)-2,3-dihydro-2,2-dimethyl-4H-1,3-benzoxazin-4-one having a melting point of 127°-129° (from isopropanol).
