Crude material from step 3 was dissolved in 1 ml DMF and 0.1 mmol DIPEA. Either 0.1 mmol phenoxyacetyl chloride were added and the reaction stirred at room temperature for 30 min, or the corresponding phenoxyacetic acid derivatives were pre-activated with HATU/DIPEA in DMF for 10 min and added to the crude material from step 3. The product was isolated via preparative high performance liquid chromatography (HPLC).
