Reaction Steps
D6 (1.67 g, 6.41 mmol), (2R,6S)-2,6-dimethylpiperazine (0.73 g, 6.41 mmol) and potassium carbonate (1.95 g, 14.1 mmol) in DMF (20 ml) were heated at 50° C. for 2 h. The mixture was concentrated and the residue partitioned between DCM and water (50 ml each). The aqueous layer was re-extracted with DCM (50 ml) and the combined organics washed with brine (100 ml), dried (Na2SO4) and concentrated to yield the title compound as an orange oil (1.88 g). δH (CDCl3) 1.25 (6H, d), 1.15 (1H, br s), 1.64-1.71 (11H, m), 2.77 (2H, m), 2.93 (2H, m), 3.59 (2H, s), 6.40 (1H, d), 8.00 (1H, d). MS (ES): MH+ 295
