実験手順

The title compound is prepared analogously as described for GP2-WU2 using 5-(3,4-diethoxyphenyl)-4,4-dimethyl-2-piperidin-4-yl-2,4-dihydro-3H-pyrazol-3-one (compound B2) and 5-(benzyloxy)-2-methylbenzoic acid (compound F1) as starting compounds. The crude product is purified by chromatography (amino phase silica gel and DCM) and by a second chromatography (silica gel and cyclohexane/EA=6:4) to yield the title compound.
