The product of Step (b) (0.15 g) was dissolved in DMF (4 ml). 3-Methylsulphonyl-benzoic acid (0.110 g), triethylamine (0.250 ml) and PyBrop® (0.350 g) were added. After 8 hours at room temperature the solvents were evaporated and the residue redissolved in ethyl acetate. The organics were washed with H2O, dried with MgSO4 and concentrated. Purification by reverse phase HPLC (with a gradient eluent system (25% MeCN/NH4OAcaq (0.1%) to 95% MeCN//NH4OAcaq (0.1%)) and formation of the hydrochloride salt by addition of HCl dissolved in ether and evaporation of solvent gave the title compound (0.145 g).
