Versuchsvorschrift
The title compound was prepared as described in General Method 3 from 3-(3-hydroxy-phenyl)-1-phenyl-prop-2-en-1-one (8.0 g, 35.7 mmol), 5% Pd on BaSO4 (0.4 g), and THF (100 mL) at a reaction time of 2 hours. The crude product was purified by silica gel chromatography, eluting with EtOAc:hexane (10:90 to 25:75) to give the title compound, m.p. 81°-83° C.
