Procedure

To a solution of example 57c (100 mg, 0.190 mmol) in DME (1 ml), and water (0.5 ml), 3,5-dimethoxy phenyl boronic acid (0.209 mmol) and sodium carbonate (40 mg, 0.380 mmol) were added and the system was degassed for 5 min. 1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) (27.8 mg, 0.038 mmol) was added under nitrogen atmosphere and the mixture was heated to 90° C. at a microwave reactor for 15 min. LC-MS analysis indicated the total consumption of example 57c, then ethyl acetate (2 ml) and water (0.5 ml) was added. The two phases were separated and the aqueous layer was extracted by ethyl acetate (1 ml). The combined organic layer was dried over Na2SO4, filtered and evaporated to dryness. The residue was purified by preparative TLC using mixture of ethyl acetate: petroleum ether in 2:1 ratio as an eluent to afford the desired compound. Brown solid (23.4 mg, 23%). MP: 224-227° C. 1H-NMR (δ ppm, CDCl3, 300 MHz): δ 8.24(s,1H), 8.21(dd, J=8.0,1.5 Hz, 1H), 7.69(m,1H), 7.48(d, J=8.4 Hz, 1H), 7.42(t, J=8.0 Hz, 1H), 7.32(m,1H), 7.04(m,3H), 6.79(d, J=2.3 Hz, 2H), 6.56(t, J=2.1 Hz, 1H), 6.11(q, J=7.2 Hz,1H), 5.58(s,2H), 3.85(s, 6H), 2.02(d, J=7.1 Hz, 3H). Mass: 537.8(M+).
