Versuchsvorschrift
(S)-2-tert-butoxy-2-(1-(4-chlorophenyl)-3-methyl-6-(pyridin-3-yl)naphthalen-2-yl)acetic acid (54) was prepared in a similar fashion to compound 53 of Example 51 with the substitution of pyridin-3-ylboronic acid for pyridin-4-ylboronic acid in step 5. The title compound (0.024 g) was isolated as an amorphous white powder.
