Reaction Steps

A mixture of Intermediate 24b (300 mg, 1.74 mmol) and Intermediate 45b (1.26 g, 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 an orange oil (350 mg, 71%). 1H NMR (400 MHz, CDCl3): 2.41-2.52 (4H, m), 2.58 (2H, t, J 5.6), 3.03 (3H, s), 3.27 (2H, t, J 6.0), 3.62 (4H, t, J 5.2), 7.04-7.08 (1H, m), 7.58-7.65 (1H, m), 8.39 (1H, t, J 2.4).
