Participants

Reaction Steps

To a cooled solution of 3-aminoethyl)-2,3,4,5-tetrahydro-1-(p-trifluoromethylphenoxy)-3-benzazepine of Example 21b (5.5 g, 0.016 mole) and triethylamine (1.8 g, 0.018 mole) in chloroform (75 ml) was slowly dropped a solution of ethyl chloroformate (2.0 g, 0.018 mole) in chloroform (25 ml). After stirring twenty hours at ambient temperature the reaction mixture was concentrated to a semisolid which was dissolved in ether, washed with water and dried (saturated NaCl, anhydrous MgSO4). The solution was filtered and concentrated to yield an oil. A sample of the resultant oil was distilled to yield an oil of 3-(2-ethoxycarbonylaminoethyl)-2,3,4,5-tetrahydro-1-(p-trifluoromethylphenoxy)-3-benzazepine, bp 235°-238° C./0.10 mm.
