Versuchsvorschrift

1-([1,11′-Biphenyl]-2-ylmethyl)-5-methoxy,y-2-methyl-1H-indole-3-acetic acid ethyl ester. 5-Methoxy-2-methyl-1H-indole-3-acetic acid ethyl ester (988 mg, 4 mmol) was added to 160 mg (4 mmol) of NaH/mineral oil (previously washed with hexane), the mixture stirred for 0.5 hours and 0.74 mL (4 mmol) of2- (bromomethyl) biphenyl added. After 2 hours, water was added and the mixture extracted with ethyl acetate. The ethyl acetate was washed with brine, dried (MgSO4) and concentrated at reduced pressure. The residue was chromatographed on silica gel eluting with 20% EtOAc/hexane to give 1.18 g (72% yield) of 1-([1,1′-biphenyl]-2-ylmethyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid ethyl ester as an oil.
