Reaction Steps

A mixture of Intermediate 24b (300 mg, 1.74 mmol) and N,N′,N′-trimethylethane-1,2-diamine (900 mg, 8.77 mmol) in NMP (2 mL) was heated in the microwave at 170° C. for 2 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 0-10% [2M NH3 in MeOH] in DCM, gave the title compound as a brown oil (190 mg, 46%). LCMS (Method 4): Rt 0.38 min, m/z 238 [MH+].
