Reaction Steps
A stirred solution of 4-amino-3-[(1-benzyl-piperidin-4-yl-amino)-methyl]-phenol (0.16 g, 0.51 mmol) in tetrahydrofuran (3 mL) at 0° C. was treated with carbonyl diimidazole (52 mg, 0.51 mmol). The reaction was stirred for 30 min at 0° C. and at reflux for 1 h. After cooling to room temperature, the solvent was evaporated and the residue purified by column to afford 100 mg (57%) of the desired product. LC/MS: tR=1.09 min, 338.28 (MH)+.
