Into a 1-Neck round-bottom flask 4-(Hydroxymethyl)piperidine (6.53 g, 56.7 mmol), Potassium carbonate (7.84 g, 56.7 mmol), Acetonitrile (50 mL, 1000 mmol), and [A] 4-Fluoronitrobenzene (4.00 g, 28.3 mmol)were added. The reaction was heated at 60° C. overnight. The reaction content was poured into ice water and stirred for 30 minutes. The solid was filtered, washed with water and dried under vacuum to give [1-(4-Nitro-phenyl)-piperidin-4-yl]-methanol as an off-white solid (5.20 g, 78%). NMR 1H (DSMO-d6)-8.02 (d, 2H, J=9.40 Hz), 7.00 (d, 2H J=9.49 Hz), 4.50 (bs, 1H), 4.07 (bd, 1H, J=13.33 Hz), 3.27 (d, 1H, J=5.84 Hz), 2.94 (t, 2H), 1.80-1.95 (m, 3H), 1.02-1.13 (m, 2H)
