Reaction Steps

The product from Step 2 (7.55 g, 26.8 mmol) in THF (80 mL) and triethylamine (3.7 mL, 26.8 mmol) was treated with aniline (2.6 g, 27.9 mmol) and allowed to stir at rt until the reaction was judged complete by TLC. The solvent was removed in vacuo and the residue dissolved in ethyl acetate, washed (3×) with water and brinde, dried over Na2SO4 and concentrated in vacuo to afford the title compound (7.65 g, 97%). MS (ES+) m/e 294/296 [M+H]+.
