Reaction Steps
Under nitrogen, sodium amide (3.5 g, 0.045 mol, 50% suspension in toluene) was added to a 100 ml three-necked roundbottom flask. The above nitrile (4.0 g, 0.011 mol) was dissolved in dry toluene (50 ml) and added. The reaction mixture was heated at reflux temperature for 16 h. After cooling to room temperature, water was added with caution (100 ml). More toluene was added and the organic phase was washed with dilute HCl. After drying (MgSO4), the organic phase was evaporated in vacuo affording 3.0 g (81%) of crude 2-(3-(10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl)-1-propyloxy)tetrahydropyran as an oil.
