“…First, 2‐bromopyridine ( 1a ) and 4‐methoxyphenyl boronic acid ( 2 ) were selected as model substrates and subjected to Suzuki‐Miyaura cross‐coupling according to Sajiki's protocol (3.5 mol% Pd/C, Na 3 PO 4 ·12H 2 O, 3 h, 80 °C, 50% i PrOH, N 2 atmosphere) [5]. Then with the coupling reaction product 3a , hydrogenation was carried out according to a previously reported protocol (10 mol% Pd/C, H 2 ‐balloon pressure) [7]. It was found that the hydrogenation of a biaryl compound required a longer reaction time of 48 h (compared to just pyridine hydrogenation, which only required 15 h) to afford 4a .…”
