Procedure: A suspension of methyl 2-(4-chloro-6-methyl-2-(piperidin-1-yl)pyrimidin-5-yl)pentanoate (0.081 g; 0.25 mmol), tetrakis(triphenylphosphine) palladium(0) (0.029 g; 0.025 mmol), N,N-diisopropylethylamine (0.172 mL; 1.00 mmol) and 2-chloro-4-methylphenylboronic acid (0.064 g; 0.375 mmol) in a mixture of DME-water (3:1, 1 mL) was heated at 100° C. in a sealed tube for 2.5 h. The mixture was diluted with brine and extracted with ethyl acetate. The combined organics were dried over magnesium sulphate, filtered and concentrated under reduced pressure. Purification by flash-chromatography on silica gel using a gradient of methanol (1-10%) in dichloromethane furnished 0.069 g (64%) of the title compound as a colorless oil. extracted with ethyl acetate The combined organics were dried over magnesium sulphate filtered concentrated under reduced pressure Purification by flash-chromatography on silica gel using a gradient of methanol (1-10%) in dichloromethane

Procedure: The title compound is prepared by following a procedure analogous to Example 113, Step 1, using N-{2-[(2-dimethylamino-ethyl)-methyl-amino]-benzothiazol-6-yl}-4-iodo-benzamide (0.40 g, 0.83 mmol) and 2-chloro-4-methyl-phenyl boronic acid (0.17 g, 0.10 mmol) to afford 2′-chloro-4′-methyl-biphenyl-4-carboxylic acid {2-[(2-dimethylamino-ethyl)-methyl-amino]-benzothiazol-6-yl}-amide (0.21 g, 0.44 mmol, 53%). The material is dissolved in EtOH, treated with 1.0 M HCl in EtOH (0.44 mL), concentrated and recrystallized from EtOH/Heptane to give 0.20 g (88%) as the hydrochloride salt.
