Procedure

The imine (Example 26A, 30 mg, 0.09 mmol) was dissolved in acetonitrile (1.5 mL). Triethylamine (19 μl, 0.18 mmol) was added followed by the 1-piperidinecarbonyl chloride (0.11 mmol). The reaction was heated at 65° C. overnight. The reaction mixture was cooled down and passed through a Si-amine cartridge (1 g, 1.6 mmol/g) to remove the excess carbamyl chloride eluting with additional acetonitrile. The resulting solution was dried and purified by reverse phase HPLC to supply the titled compound. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.40 (4 H), 1.53 (2 H), 2.20 (3 H), 3.43 (4 H), 7.24 (1 H), 7.63 (2 H), 7.83 (1 H); MS (ESI) m/z 432.2 (M+H)+.
