1-(4-Fluorophenyl)-2-methyl-2-aminopropane → 6-benzyloxy-8-{2-[2-(4-fluoro-phenyl)-1,1-dimethyl-ethylamino]-1-hydroxy-ethyl}-2,2-dimethyl-4H-benzo[1,4]oxazin-3-one

Participants

Reaction Steps

385 mg (1 mmol) 6-benzyloxy-8-(2-ethoxy-2-hydroxy-acetyl)-2,2-dimethyl-4H-benzo[1,4]oxazin-3-one and 167 mg (1 mmol) 2-(4-fluoro-phenyl)-1,1-dimethyl-ethylamine are reacted and worked up analogously to Example 14. However, the resulting benzylether is chromatographed on a silica gel column (dichloromethane/methanol gradient).
