US federal budgets, which you can find searching google books, show remittances to London & Amsterdam for interest payments on "Louisiana stock" during the war years.

This question was much harder to research than I expected - despite (eventual) availability of the Barings Bank Archive web site. What I was able to determine is that:
Barings Brothers forced a reduction in the Louisiana Purchase price, from 100M French Francs to 80M French Francs, because the original asked amount was greater than it was possible to finance.
Baring Brothers remained the official agent of the U.S. Government through the War of 1812, and financed it during that war.
Baring Brothers continued as dominant to its rivals in North America even after being surpassed in London itself by Rothschild's.
Baring Brothers held an overwhelming position in the financing of early U.S. railroads through most of the 19th century.
Baring explicitly requested, and received, permission from the British government to finance the issue - as the benefit of security for British North America was expected to outweigh any advantage gained by Napoleon from the Louisiana Sale.
In this case, to paraphrase Holmes from Sir Arthur Conan Doyle's Silver Blaze:
Or more bluntly, I find it inconceivable that a default or refinancing of this debt could have completely disappeared from the historical record.
From my comment below:
I read a couple of chapters of an old treatise on the early merchant bankers researching this - and it basically confessed that no-one knows how either Barings or Rothschilds transported much of their assets across the Atlantic. Either trade secret, or still classified in the Admiralty office. Recall though that by late 1814 the New England states were on the verge of secession over the war. Smuggling British ships in and out of Boston would likely not have been difficult.
