The mixture was stirred at 60° C. for 1.5 h then allowed to cool to RT. The mixture was carefully quenched by pouring into MeOH (10 mL), then applied to an SCX-2 cartridge and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-10% [2M NH3 in MeOH] in DCM, gave the title compound as a brown solid (180 mg, 75%). LCMS (Method 4): Rt 0.49, m/z 378 [MH+].
