Combine 6-Methoxy-10-(4-methoxy-phenyl)-1,2,3,4,4a,9,10,10a-octahydro-phenanthrene (chiral) (0.02 g, 0.32 mmol) and methylene chloride (10 ml) and add bromine (0.0162 ml, 0.32 mmol) at 0-5° C. over 15 minutes. Stir as such one hour. Remove volatiles in vacuo at 40° C. to yield the titled compound (0.16 g, 100%). 1H NMR (CDCl3): 7.38 (s, 1H), 7.25 (d, J=8.8 Hz, 2H), 6.9 (m, 3H), 3.93 (s, 3H), 3.85 (s, 3H), 3.2 (m, 3H), 2.85 (dd, J=4 and 11, 1H), 2.48 (d, J=14 Hz, 1H), 2.06 (m, 1H), 1.8-0.8 (m, 7H).
