The isopropyl chloroformate (18.4 mg, 0.15 mmol) was dissolved in anhydrous tetrahydrofuran (0.05 mL) and cooled at −40° C. A solution of amine from Example 8A (33.7 mg, 0.1 mmol) and triethylamine (0.021 mL, 0.15 mmol) in anhydrous tetrahydrofuran (0.5 mL) was added at −40° C. and reaction allowed to warm at room temperature, shaken overnight, then concentrated under reduced pressure. The residue was purified by reverse-phase HPLC to provide the title compound. Yield: 10.7 mg (25%). 1H NMR (500 MHz, DMSO-d6) δ 1.05 (m, 12H), 2.11 (m, 1H), 2.33 (d, J=17.15 Hz, 1H), 2.50 (m, 1H), 2.73 (m, 2H), 2.99 (d, J=16.53 Hz, 1H), 3.44 (m, 4H), 4.70 (m, 1H), 7.07 (m, 4H), 7.67 (d, J=15.0 Hz, 4H), 9.88 (s, 1H), 10.95 (s, 1H); MS (ESI): 424 (M+H)+, 422 (M−H)−.
