A mixture of Intermediate 24b (400 mg, 2.32 mmol) and Intermediate 79b (1.33 g, 11.6 mmol) in NMP (5 mL) was heated in the microwave at 170° C. for 3 h. The reaction mixture was applied to an SCX-2 cartridge (25 g) and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-8% [2M NH3 in MeOH] in DCM, gave the title compound (190 mg, 32%). LCMS (Method 1): Rt 2.01 min, m/z 251 [MH+].
