Reaction Steps

The product of step (iii) (0.2 g) was dissolved in dichloromethane (5 ml), triethylamine (0.126 ml) and 4-methylbenzoyl chloride (0.097 ml) were added. After 2 hours at room temperature, ethyl acetate and aqueous NaHCO3 solution were added, the organic phase separated and the solvent removed to leave an oil. Purification by reverse phase HPLC (with a gradient eluent system (25% MeCN/NH4OAcaq (0.1%) to 95% MeCN//NH4OAcaq (0.1%)) gave a gum. Addition of 1.0M ethereal hydrogen chloride solution gave the titled product as a solid (0.104 g).
