Procedure

To a solution of (1R,2S)-2-methoxyindan-1-amine (242.8 mg, 0.001488 mol) in THF (1 mL) was added cyanuric chloride (313 mg, 0.00170 mol) at 0° C., followed by DIPEA (300 μL, 0.002 mol) and the reaction was stirred at 0° C. for 1.5 hours. The reaction was poured into water and extracted with CH2Cl2. The organic layer was dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (0 to 15% EtOAc/hexanes) to obtain 229.1 mg (49%) of the title compound. LC/MS: Rt=2.03 min, ES+ 311 (FA standard).
