Procedure

To a sealed tube containing 10 mL 2.0 M methylamine in methanol was added 16.5 mg (0.03 mmol) of ATL146e. The flask was sealed and allowed to stir at 70° C. for 120 hours. The vessel was cooled to 0° C., opened, and the solvent was removed in vacuo to yield 8.0 mg (48%) of JR3065 as a white solid after the residue was purified by RP-HPLC. 1H NMR (CD3OD-d4) δ. 13C NMR (CD3OD-d4) δ. APCI m/z (rel intensity) 486.3 (MH+, 100), 313.4(35).
