Reaction Steps

2-(4-Bromophenyl)-N-isobutyl-2-methylpropanamide (Example 1a) (850 mg, 2,85 mmol) was dissolved in 30 ml of toluene, 6 ml of EtOH and 4.5 ml of water followed by 1.38 g (10 mmol) of K2CO3 and 560 mg (5 mmol) of 3-furanboronic acid. The suspension was degassed using argon stream and sonication (30 min). Then 1.16 g (1 mmol) of tetrakis(triphenylphosphine)palladium was added under argon and the mixture was stirred at 80° C. overnight. The solution was dried down on vacuum, diluted with EtOAc and extracted with water. The organic phase was dried over MgSO4 and evaporated on vacuum providing a crude product that was further purified using RP HPLC yielding 300 mg (41%) of the title compound as a white solid. 1H NMR (400 MHz, dDMSO): δ 0.74-0.75 (d 6H), 1.45 (s, 6H), 1.67-1.70 (m,1H), 2.83-2.86 (dd, 2H), 6.94-6.95 (dd, 1H), 7.30-7.32 (m, 3H), 7.54-7.57 (m, 2H), 7.72-7.73 (t, 1H), 8.15-8.16 (t, 1H). MS (M+H, 286).
