A process for efficiently producing, through few steps either a xanthine oxidase inhibitor, which is a therapeutic agent for hyperuricemia, or an intermediate therefore. The process is a novel coupling process which comprises subjecting a compound represented by formula (1) to coupling reaction with a compound represented by formula (2) in the presence of a transition metal compound to thereby obtain a compound represented by formula (3).

The invention is directed to a class of compounds, including the pharmaceutically acceptable salts of the compounds, having the structure of formula (I) as defined in the specification. The invention is also directed to compositions containing and uses of the compounds of formula I.
The present invention provides a (meth)acrylate manufacturing method characterized in that when manufacturing a (meth) acrylate by an ester exchange reaction between an alcohol and a monofunctional (meth)acrylate using catalyst A and catalyst B together, contact treatment of the ester exchange reaction product with adsorbent C is performed. Catalyst A: One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure and salts or complexes thereof, amidine and salts or complexes thereof, compounds with a pyridine ring and salts or complexes thereof, phosphines and salts or complexes thereof, and compounds with a tertiary diamine structure and salts or complexes thereof. Catalyst B: One or more kinds of compounds selected from a group consisting of compounds comprising zinc. Adsorbent C: One or more kinds of compounds selected from a group consisting of oxides and hydroxides comprising at least one of magnesium, aluminum and silicon.
