*Judge orders Nacchio to report to prison on April 14

*Rejects bid to remain free pending appeal

DENVER, April 7 (Reuters) - A federal judge on Tuesday ordered Qwest Communications International Q.N ex-Chief Executive Joseph Nacchio to surrender to a federal prison next week, rejecting his bid to remain free while he pursues an appeal of his insider trading conviction to the U.S. Supreme Court.

U.S. District Judge Marcia Krieger ordered Nacchio to report to minimum security prison near Minersville, Pennsylvania on April 14 by noon (1600 GMT) to begin serving a six-year sentence.

“The court finds that the defendant has not established a substantial question of fact or law... that there would be a reversal of his conviction, new trial or abrogation of his sentence,” Krieger wrote in an opinion filed on Tuesday.

Krieger previously had set March 23 as Nacchio’s surrender date but set it aside while she reviewed his high court petition.

Nacchio’s attorneys have said they would take his petition to remain free to the 10th U.S. Circuit Court of Appeals if Krieger denied it.

Nacchio was convicted in 2007 of selling $52 million of his Qwest stock in 2001 while withholding from investors information that the telecommunications company would miss its financial targets. (Reporting by Robert Boczkiewicz in Denver; Editing by Tim Dobbyn)
