Versuchsvorschrift

This compound was prepared from 4-benzyloxyaniline hydrochloride (4.0 g, 17.0 mmol) and 5-methylpyrazole-2-carboxylic acid (2.25 g, 17.8 mmol), using the same method used to prepare pyridine-2-carboxylic acid (4-benzyloxyphenyl)amide, to give the product as a solid. The product was used without further purification in the subsequent reaction. MS m/z 308 (MH+). 1H NMR(CDCl3+MeOD-d4) δ 2.34 (s, 3H), 5.06 (s, 2H), 6.62 (s, 1H), 6.96 (d, 2H), 7.31 (m, 7H) and 7.58 (d, 1H).
