Reaktionsschritte
The title compound is prepared analogously as described for GP2-WU2 using 5-(7-methoxy-2,2-dimethyl-2,3-dihydro-1-benzofuran-4-yl)-4,4-dimethyl-2-piperidin-4-yl-2,4-dihydro-3H-pyrazol-3-one (compound B5) and 2,4-dimethoxybenzoic acid as starting compounds. The crude product is purified by chromatography (amino phase silica gel and DCM) and by crystallization from DCM and diethyl ether to yield the title compound.
