About 60 protesters, thought to be part of Occupy London Stock Exchange (OLSX), tried to get into Panton House on Panton Street, off Haymarket.
Riot police entered and clred the building and 21 arrests have been made.
An OLSX spokesman said protesters were targeting Mick Davis, chief executive of mining company Xstrata, which has s in the building.
He said they were targeting Mr Davis because he was one of the highest paid chief executives from FTSE 100 companies in the past yr.
Occupy London supporter Karen Lincoln said: "Mick Davis is a prime example of the greedy 1% lining their own pockets while denying workers pensions."
An Xstrata spokeswoman said: "All executive pay is approved by the company's shareholders and is linked to company and individual performance.
"Last yr Xstrata delivered its second best financial performance since inception, with an 86% incrse in profits, record cost savings, improved safety performance and total shareholder returns substantially grter than the FTSE 100 average."
Police said the incident was isolated and not related to the march and rally in support of public sector workers "which passed off pcefully".
A total of 21 people were arrested for a variety of offences including burglary, aggravated trespass, criminal damage and assault on a police r.
'Shame on you'The protesters gathered at Piccadilly Circus just before 15:30 GMT.
Most were held at bay by police but a few got inside and went on to the roof, where rs moved in to clr them.
Police vans were seen pulling up at the scene in Haymarket while protesters were contained in the ar outside Panton House.
Police sled off the ar around Panton Street and marched through the 200 to 300 protesters, to shouts of "shame on you".
Police told the protesters by megaphone announcement from a van: "You are being contained because we fr an imminent brch of the pce will occur.
"You will be relsed as soon as possible."
Police said they were in the process of making a of arrests for aggravated trespass.
A Scotland Yard spokesman said: "At approximately 15:50 GMT a containment was put in place outside Panton House, Haymarket, to prevent disorder by a group of protesters outside the building.
"Some protesters have entered the building and rs are in the process of making arrests for aggravated trespass."
Since the Occupy movement protests began in New York, in September, a protest camp has been set up by the group in the City of London.
