Versuchsvorschrift

Compound 43 (38 mg, 0.066 mmol) was dissolved in dioxane/water 1:1 (4 mL) and the solution was cooled to 0° C. and 1 M LiOH (132 ul, 0.132 mmol) was added. The temperature was raised to room temperature and the solution was stirred for 2 hours after which it was neutralized by addition of 1M HCl and evaporated and coevaporated with toluene. The residue and deprotected amine 38 (1.1 eq) was dissolved in DMF and coupled using the standard HATU coupling conditions as in the synthesis of compound 34. The crude product was extracted with EtOAc, washed with brine, dried, filtered and concentrated. Purification with HPLC (MeOH/water 9:1+0.2% TEA) provided compound 44 (44 mg, 81%) as a colorless solid.
