Prosecutors are asking a federal judge in Boston to send Robert A. George, a prominent criminal defense lawyer convicted of money laundering, to prison for more than five years when he is sentenced on Wednesday.

In a court filing on Tuesday, prosecutors requested a 63-month prison term for George. His sentencing is scheduled for 11 a.m. in federal court in Boston, where he was convicted of helping a former client launder $200,000 in profits from crimes.
