    NEW YORK – Madonna has sued the people who run her luxury co–op building overlooking the Central Park for refusing her request to buy a neighbor’s apartment.

    Madonna claimed in court papers that the co–op’s board of directors wrongfully blocked her purchase of the seventh–floor apartment at West 64th street on the Upper West Side. The Material Girl actress, who already owns a large apartment in the building, is asking the court to let the sale go through and award her legal fees, according to a notice field Wednesday in Manhattan’s State Supreme Court. The 49–year–old singer moved into the building after she was rejected by the board at the Ritzy San Remo co–op in 1985 presently home to U2 frontman, Bono Midboro Management Inc., the company that manages the West 64th street building, refused to give comments on the dispute, and the co–op board president did not answer a call on Friday for comment.
