Reaction Steps

The compound 262 (286 mg, 1 eq.) in degazed dimethylacetamide (10 mL), and Zn (4.5 mg, 0.09 eq.), Zn(CN)2 (84 mg, 0.6 eq.), Pd2dba3 (21 mg, 0.03 eq.), and dppf (26 mg, 0.06 eq.) were heated at 110° C. under microwaves for 30 min. Then, water was added, the precipitate filtered and dissolved in ethyl acetate, dried, and concentrated under vacuum. The residue was purified by chromatography on a silica gel to give compound 263 as a yellow solid in 81% yield. 1H NMR (CDCl3, 400 MHz) δ (ppm) 4.07 (s, 3H), 6.79 (br s, 1H), 7.08 (d, J=9.11 Hz, 1H), 8.19 (s, 1H), 8.28 (d, J=9.11 Hz, 1H), 9.74 (br s, 1H); MS (ESI, EI+): m/z=318.15 (MH+).
