To a suspension of [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-(4-phenyl-4,5,6,7-tetrahydro-benzothiazol-2-yl)-amine (200 mg, 0.48 mmol) in dichloroethane (4.8 mL) was added under nitrogen at room temperature borontribromide (528 uL, 0.53 mmol) and the reaction was refluxed for 2 hours. The same amount of borontribromide was added and the reaction was refluxed for 2 hours, again the same amount of borontribromide was added and the reaction was refluxed for 1 hour, stirred at room temperature for 3 days. The reaction was set to pH 7 with aqueous sodium hydroxide and extracted three times with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and the solvent was removed under reduced pressure. The residue was purified on silica gel using dichloromethane/methanol/concentrated aqueous ammonia (9:1:0.1 v/v/v) as eluent to yield the title compound (70 mg, 36%) as a beige solid. MS ISP (m/e): 403.3 (100) [(M+H)+]. 1H NMR (DMSO-D6, 300 MHz): δ (ppm)=10.06 (s, 2H), 7.64 (s, 1H), 7.25-7.31 (m, 2H), 7.17 (t, 1H), 7.00-7.11 (m, 6H), 4.04 (m, 1H), 2.71 (m, 2H), 2.19 (m, 1H), 2.13 (s, 3H), 1.66-1.85 (m, 3H).
