The amine was reacted with Compound 525c (0.314 g, 0.805 mmol) in the presence of HBTU (0.32 g, 0.844 mmol) and DIEA (0.47 mL, 2.68 mmol) in DMF (10 mL), followed cyclization in AcOH (10 mL) according to procedure (2) and (3) in the preparation of Compound 477d. Separation by RP HPLC (from 20% of buffer B to 99% of buffer B) gave the title intermediate (0.19 g, 40%).
