Participants

Reaction Steps

A solution of the compound (0.050 g, 0.12 mmol) of Example 108, ethylene glycol (0.20 mL, 3.6 mmol), 4-dimethylaminopyridine (0.0030 g, 0.024 mmol) and zinc cluster catalyst (Zn4(OCOCF3)6O) (0.0058 g, 0.0061 mmol) in N,N-dimethylacetamide (0.5 mL) was stirred with the microwave synthesizer (Biotage Initiator™) at 150° C. for 30 min. Cooled to ambient temperature, the precipitate was removed by filtration. The filtrate was purified by preparative HPLC to afford the titled compound as solid (0.0061 g, y. 10%).
