The product of Example 1, Step 3 (15.2 g, 78.7 mmol), 4-benzyloxyaniline HCl (15.6 g, 78.7 mmol) and Et3N (27 mL, 196.9 mmol) were combined in DMF (125 mL) and heated to 60° C. for 1 h. The reaction mixture was cooled and H2O (200 mL) was added dropwise over 1 h. The resulting yellow/orange precipitate was filtered and washed with Et2O to provide the title compound as a yellow powder (25.8 g, 92%). MS (ES+) m/e 356 [M+H]+.
