To a sealed tube containing 10 mL of saturated MeOH/NH3 solution was added 5 mg (0.01 mmol) of ATL146e. The flask was sealed and allowed to stir at 25° C. for 48 hours. The vessel was cooled to 0° C., opened, and the ammonia removed by bubbling N2 for 1 hour. The remaining solvent was then removed in vacuo to yield 4.0 mg (83%) of JR3055 as a white solid after the residue was purified by RP-HPLC. 1H NMR (CD3OD-d4) δ 8.41 (s, 1H), 5.98 (d, J=7.2 Hz, 1H), 4.65 (dd, J=7.3 Hz, 4.8 Hz, 1H), 4.41 (d, J=2.0 Hz, 1H), 4.28 (dd, J=4.6 Hz, 2.0 Hz, 1H), 3.35 (m, 2H), 2,37 (d, J=6,4 Hz, 2H) 2.10 (m, 1H), 1.90 (m, _H), 1.53 (m, _H_), 1.23 (m, 13H), 1,12 (t, J=7.3 Hz, 3H). 13C NMR (CD3OD-d4) δ. APCI m/z (rel intensity) 472.3 (MH+, 100), 299.4(10).
