Reaktionsschritte
N-nitroso-N-propylaniline, prepared from N-n-propylaniline by the same method as described in Example 1, was conveniently reduced with lithium aluminum hydride (LAH). The LAH in 450 ml dry ether was heated under reflux for 15 minutes, and a solution of 32.8 g (0.2 mol) crude 4 in 250 ml dry ether was added dropwise. The reaction mixture was allowed to stir for 3 hours before it was quenched by the dropwise addition of 12 ml water and 14 ml 20% sodium hydroxide. The resultant suspension was filtered free of inorganic salts, dried and stripped of solvents under diminished pressure. Distillation of the residue yielded the desired compound bp 55°-57°/0.12 mm.
