Reaction Steps

The above phenol (1.20 g, 3.91 mmol) was reacted with 4-(tert-butyl)phenylboronic acid (1.6 eq., 6.26 mmol, 1.11 g ), copper(II) acetate (1.0 eq. 3.91 mmol, 710 mg) as desribed in general procedure G. Flash column chromatography on silica (ethyl acetate/hexanes) provided 750 mg of the desired product, (3S)-7-(4-tert-butylphenoxy)-3,4-dihydro-1H-isoquinoline-2,3-dicarboxylic acid 2-tert-butyl ester 3-methyl ester.
