Reaction Steps

3-Bromopheylurea (10.40 g), 2-thiopheneboronic acid (8.20 g) and palladium tetrakistriphenylphosphine (2.63 g) were added to a flask containing 300 mL of dimethoxyethane and 100 mL of 2.0 M aqueous potassium carbonate under an atmosphere of dry N2. The reaction mixture was heated at 90° C. overnight. The reaction mixture was then cooled to room temperature and partitioned between EtOAc and water. The EtOAc layer was dried over MgSO4, filtered and concentrated under vacuum. The resulting residue was tritutrated with ethyl ether to give 9.00 g of 1-(3-(thiophen-2-yl)phenyl)urea.
