Versuchsvorschrift

A mixture of Example 9a (0.094 g, 0.2 mmol), cyclopentanamine (0.034 g, 0.4 mmol), and triethylamine (0.081 g, 0.8 mmol) in DMSO (2 mL) was heated at 120° C. overnight. The reaction mixture was purified by preparative HPLC (C18, 10-80% acetonitrile in 0.1% TFA/water to afford 0.019 g of the title product. 1H NMR (500 MHz, DMSO-d6) δ 1.27 (t, J=7.02 Hz, 3H), 1.32-1.36 (m, 2H), 1.47-1.55 (m, 3H), 1.88-1.93 (m, 2H), 3.55 (s, 3H), 3.83-3.88 (m, 1H), 4.22 (q, J=7.02 Hz, 2H), 5.94 (t, J=2.29 Hz, 1H), 6.77 (d, J=8.85 Hz, 1H), 7.22 (s, 1H), 7.28 (t, J=2.75 Hz, 1H), 7.63 (d, J=1.83 Hz, 1H), 7.82 (dd, J=8.54, 2.14, 1H), 12.01 (s, 1H). MS (ESI+) m/z 380.2 (M+H)+.
