Reaction Steps
The title compound is prepared analogously as described for GP1 using 5-(3,4-dimethoxyphenyl)-4,4-dimethyl-2-(piperidin-4-yl)-2,4-dihydro-3H-pyrazol-3-one hydrochloride (compound B1*HCl) and 3-nitrobenzoyl chloride as starting compounds. The crude product is purified by column chromatography (silica gel and DCM/EA=1:1) and by crystallization from EA and diethyl ether to yield 5-(3,4-dimethoxyphenyl)-4,4-dimethyl-2-{1-[(3-nitrophenyl)carbonyl]piperidin-4-yl}-2,4-dihydro-3H-pyrazol-3-one as the product.
