Reaction Steps

The imine (Example 26A, 30 mg, 0.09 mmol) was dissolved in dichloromethane (1.5 mL). Diisopropylethylamine (31 μl, 0.18 mmol, 2 equiv.) was added followed by the methanesulfonyl chloride (0.1 mmol, 1.1 equiv.). The reaction was stirred at room temperature for 4 hours. The reaction mixture was passed through a Si-amine cartridge (1 g, 1.6 mmol/g) to remove the excess sulfonyl chloride and washed with additional dichloromethane. The resulting solution was dried, concentrated, and purified by reverse phase HPLC. 1H NMR (500 MHz, DMSO-d6) δ ppm 2.24 (3 H), 2.90-2.96 (3 H), 7.31 (1 H), 7.56 (1 H), 7.68 (1 H), 7.83 (1 H); MS (ESI) m/z 398.9 (M+H)+.
