Procedure
This compound was prepared from 4-benzyloxyaniline hydrochloride (4.0 g, 17.0 mmol) and (−)-N-carbobenzyloxy-l-proline (4.44 g, 17.8 mmol), using the same method to prepare pyridine-2-carboxylic acid (4-benzyloxyphenyl)amide, to give the product as a colorless solid, 7.51 g (98%), which was used without further purification in the subsequent step. MS m/z 431 (MH+). 1H NMR(CDCl3) δ 1.83-2.61 (m, 4H), 3.44-3.65 (m, 2H), 4.40-4.55 (m, 1H), 5.03 (s, 2H), 5.22 (br s, 2H), 6.90 (d, 2H) and 7.20-7.45 (m, 12H).
