Reaction Steps

The title compound is prepared analogously as described for GP1 using 5-(3-hydroxy-4-methoxyphenyl)-4,4-dimethyl-2-piperidin-4-yl-2,4-dihydro-3H-pyrazol-3-one hydrochloride (compound B11*HCl) and 2-methoxybenzoyl chloride as starting compounds. The crude product is purified by crystallization from EA and diethyl ether to yield 5-(3-hydroxy-4-methoxyphenyl)-2-{1-[(2-methoxyphenyl)carbonyl]piperidin-4-yl}-4,4-dimethyl-2,4-dihydro-3H-pyrazol-3-one as the product.
