To a solution of 7a (136 mg, 0.16 mmol) and tetrakis(triphenyl-
phosphine)palladium(0) (10 mg, 0.008 mmol) in toluene
(20 mL) under dry nitrogen, was added, subsequently, a suspen-
sion of 4-(dimethylamino)phenylboronic acid (35 mg,
0.21 mmol) in ethanol (25 mL) and a solution of anhydrous
sodium carbonate (45 mg, 0.42 mmol) in water (5 mL). The
mixture was then heated under reflux for 16 h. Then, the solu-
tion was allowed to cool to room temperature and toluene
(30 mL) was added to dilute the organic phase. The aqueous
phase was removed and extracted with toluene (3 × 30 mL).
The organic phases were combined and dried (MgSO4). The
solvents were reduced in volume and the crude product was pre-
cipitated with petroleum ether (40–60 °C). The product was
isolated by column chromatography (neutral alumina, toluene/
ethyl acetate 9:1 (v/v) with gradual change to ethyl acetate). The
solvents were reduced in volume and the product was precipi-
tated with petroleum ether (40–60 °C) to afford 1a as a red solid

Compound 1b was prepared as described for 1a from com-
pound 7b (78 mg, 0.10 mmol) in toluene (20 mL), tetrakis(tri-
phenylphosphine)palladium(0) (6 mg, 0.005 mmol), 4-(di-
methylamino)phenylboronic acid) (22 mg, 0.13 mmol) in
ethanol (25 mL) and anhydrous sodium carbonate (28 mg,
0.26 mmol) in water (5 mL). The product was isolated by
column chromatography (neutral alumina, toluene/ethyl acetate
9:1 (v/v) with a gradual change to ethyl acetate). The solvents
were reduced in volume and the product precipitated with petro-
leum ether (40–60 °C) to afford 1b as a red solid (36 mg, 44%);
