실험 절차

Part A: Ethyl 1-(3-cyano-4-methylphenyl)-3-methyl-5-pyrazole-carboxylate was prepared as colorless crystals following the standard condensation (3-cyano-4-methylphenyl-hydrazine and ethyl 2-(N-(methoxy)imino)-4-oxopentanoate in acetic acid) reaction protocol discussed previously. 1HNMR (CDCl3) δ: 7.68 (s, 1H), 7.57 (dd, 1H), 7.58 (d, 1H), 6.82 (s, 1H), 4.24 (q, 2H), 2.40 (s, 3H0, 2.37 (s, 3H), 1.27 (t, 3H) ppm; ESI mass spectrum analysis (270 (M+H, 100).
