Procedure

The procedure used in Example 1: step c was followed using 4-(4-amino-3-bromo-benzenesulfonyl)-5-methylsulfanyl-thiophene-2-carboxylic acid amide ((Example 319: part d) 44 mg, 0.11 mmol), 2-methylphenylboronic acid (54 mg, 0.4 mmol), aq Na2CO3 (2M, 800 μL, 1.6 mmol), and Pd(PPh3)4 (29 mg, 0.025 mmol). Analogous workup and purification by preparative TLC yielded the title compound (24 mg, 56%). 1H-NMR (CDCl3): δ 7.97 (s, 1H), 7.76 (dd, 1H, J=2.3, 8.6 Hz), 7.67 (d, 1H, J=2.3 Hz), 7.32 (m, 2H), 7.28 (m, 1H), 7.16 (m, 1H), 6.76 (d, 1H, J=8.6 Hz), 4.11 (s, 2H), 2.58 (s, 3H), 2.13 (s, 3H).
