Versuchsvorschrift

3-Amino-5-(3-ethoxypropyl)-5H-dibenzo[a,d]cyclohepten-5-ol (10 g., 0.032 mole) and sodium borohydride (12.3 g., 0.325 mole) are ground together in a mortar. The mixture is added in portions to 250 ml. of trifluoroacetic acid, cooled in ice, and stirred vigorously under a stream of nitrogen in an efficient fume hood. Upon completion of the addition, the mixture is stirred for 15 minutes and the bulk of the trifluoroacetic acid removed under vacuum.
