実験手順
The title compound is prepared analogously as described for GP2-WU2 using 5-(3,4-dimethoxyphenyl)-4,4-dimethyl-2-(piperidin-4-yl)-2,4-dihydro-3H-pyrazol-3-one (compound B1) and 2-methylnaphthalene-1-carboxylic acid as starting compounds. The crude product is purified by chromatography (amino phase silica gel and DCM) and by crystallization from diethyl ether to yield the title compound.
