実験手順

A solution of 1-phenyl-5-propyl-1H-pyrazole-4-carbonyl chloride (2.0 g, 8 mmol) in 20 mL of methylene chloride was added dropwise under nitrogen to a mixture of 6-aminomethyl-naphthalen-2-ol (1.63 g, 9.42 mmol), prepared in step 1 of Example 8, and 75 mL of anhydrous pyridine. The reaction stirred at room temperature for 17 h (overnight). The reaction was diluted with methylene chloride and extracted with 1N HCl. The aqueous layer was separated and extracted with methylene chloride. The organic extracts were combined, dried (MgSO4) and the solvent removed under reduced pressure to give a brown solid. The solid was recrystallized from ethyl acetate and then again from isopropanol. The crystals were collected by filtration and dried under reduced pressure to give 1-phenyl-5-propyl-1H-pyrazole-4-carboxylic acid (6-hydroxy-naphthalen-2-ylmethyl)-amide (0.767 g, 25%) as a tan solid, mp 189-190° C.
