The lipase-catalyzed resolution of 2-(acyloxymethyl)-4,5-dihydro-5-methylpyridazin-3(2H)-one derivatives in organic solvents containing water was demonstrated to be a practical method for the synthesis of a chiral pyridazinone bearing a pyrazolopyridine ring, which is a potent phosphodiesterase inhibitor.
