A solution of the intermediate from Step D (0.3684 g, 1.092 mmol) and ammonia (11.70 mL, 82 mmol, 7 N in MeOH) was heated at 50° C. under N2 in a screw cap vial for 24 h. The reaction mixture was concentrated in vacuo to remove the excess amine to afford the desired product, as a yellow solid. m/z=309.1 (M+H).
