Participants

Reaction Steps

A mixture of Example 1A (0.15 g, 0.7 mmol), Example 1B (0.20 g, 0.8 mmol) and tetrabutylammonium iodide (0.13 g, 0.36 mmol) in N,N-dimethylformamide (0.2 mL) was heated at 95° C. for 16 hr, cooled to room temperature and quenched with 1M NaHCO3 (10 mL). The aqueous layer was extracted with dichloromethane (3×10 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated to afford 0.2 g (crude) of the title compound. LC/MS (ESI+) m/z 294 (M+H)+.
