SL Green Realty Corp. is in contract to purchase the office portion of Manhattan’s 500 Park Ave., the former headquarters of PepsiCo Inc., from Morgan Stanley.

The real estate investment trust agreed to buy the 200,000-square-foot office portion of the building, originally known as the Pepsi-Cola Building as it housed the beverage brand’s headquarters, from Morgan Stanley (MS) Prime Property Fund, sources said. Bloomberg first reported the sale.

SL Green bought a boutique office condominium from Morgan Stanley, which listed the 11-story property two months ago.

SL Green agreed to buy the 11-story office condo at the building, located at the corner of 59th Street, for roughly $130 million, according to people familiar with the deal, who asked not to be named discussing a private matter.
