The method of Example 1 was followed using 1 eq each of 4-chloro-3-nitropyridine, tert-butyl piperidin-3-ylmethylcarbamate and diisopropylethylamine yielding tert-butyl (1-(3-nitropyridin-4-yl)piperidin-3-yl)methylcarbamate (99%). LCMS (m/z): 336.9 (MH+); LC Rt=2.27 min. 1H NMR (CDCl3): δ 8.80 (s, 1H), 8.33 (d, J=6.0 Hz, 1H), 6.85 (d, J=6.3 Hz, 1H), 4.63 (bs, 1H), 3.28-3.46 (m, 2H), 2.89-3.15 (m, 3H), 2.69-2.86 (m, 1H), 1.55-1.99 (m, 5H), 1.45 (s, 9H).
