The mixture of 4-pyridineboronic acid (0.97 g, 7.8 mmol), 4-Boc-aminopiperidine (3.25 g, 15.8 mmol), Cu(OAc)2 (2.88 g, 15.8 mmol), DMAP (catalytic amount), pyridine (2.5 mL, 32 mmol), 4A activated molecular sieve in 50 mL dry DCM was stirred for over 2 days. It was diluted with DCM, filtered through celite. It was washed with brine and water, dried, filtered through a silica plug, evaporated in vacuuo to give 4-(4-Boc-aminopiperidin-1-yl)pyridine in 90% yield. ES-MS: (+H) 278.
