실험 절차
4-Chloro-N1-(tetrahydro-pyran-4-ylmethyl)-benzene-1,2-diamine (1.026 g; 4.261 mmol) is dissolved in ethanol (65 mL) and cyanogen bromide (0.903 g; 8.522 mmol) is added. The reaction is stirred at room temperature overnight. After this time the mixture is concentrated in vacuo to afford title compound as a tan solid which was used without further purification. ESI m/z 266 [M+H]+/264 [M−H]−
