Procedure

Following the procedure as described ion Example 32, except using material from Example 44 (21.4 mg, 0.031 mmol), EtOH/H2O (4:1) (2.0 mL) and sodium borohydride (7.2 mg, 0.190 mmol), the title compound is isolated (quantitative yield) and is used crude, “as is”, in the macrocyclization step. LC/MS (Condition A): ret. T=1.90 min, (M+Na) 601.29.
