Reaction Steps

In a microwave tube were charged with compound 23B (100 mg, 0.2 mmol), 1H-1,2,4-triazole (42 mg, 0.6 mmol), triethylamine (84 μL, 0.6 mmol) and DMF (0.6 mL, The mixture was heated up to 120° C. for 15 min in a Microwave Synthesizer. After cooled down, it was partitioned between ethyl acetate and 5% of LiCl aqueous solution. The organic layer was separated and concentrated. The residue was purified on silica gel chromatography eluting with ethyl acetate and hexanes to afford the title compound. MS (m/z) 481.21 [M+H]+.
