Procedure

To a solution of 2-nitro-6-(piperidin-3-ylmethoxy)benzonitrile hydrochloride (Example 220d) (0.10 g, 0.34 mmol) in THF (6 mL) were added triethylamine (0.10 mL, 0.76 mmol) and propylisocyanate (0.05 mL, 0.52 mmol) and the reaction mixture was stirred at r.t. under nitrogen for 3 hour then filtered and evaporated, to give 3-((2-cyano-3-nitrophenoxy)methyl)-N-propylpiperidine-1-carboxamide (0.13 g, 100%). 1H NMR (400 MHz, DMSO-d6) δ 0.81 (t, J=7.2 Hz, 3H), 1.34-1.41 (m, 4H), 1.62-1.64 (bm, 1H), 1.87-1.95 (bm, 2H), 2.64-2.77 (m, 2H), 2.93-2.98 (m, 2H), 3.77 (bd, J=12.8 Hz, 1H), 3.98 (bd, J=12.8 Hz, 1H), 4.09-4.13 (m, 1H), 4.17-4.20 (m, 1H), 6.38 (d, J=5.6 Hz, NH), 7.74 (bdd, J=1.6 Hz, J=8.0 Hz, 1H), 7.88-7.94 (m, 2H). MS 347 (MH+).
