In order to synthesize PFPA and PCPA, the intermediate BPYA underwent Suzuki reactions with 4fluorophenyl-boronic acid (FPBA) and 4-(methoxycarbonyl)phenyl)boronic acid (m-CPBA), respectively (Scheme 1). PFPA was isolated directly after column chromatography with a 46 % yield, while the methyl-protected intermediate obtained in a 56 % yield was treated with LiOH to eventually obtain the final product PCPA with a 61 % yield. Detailed description of the synthetic procedures and full NMR and MS characterization of the products are shown in the SI.
