Yes, there are some methods, although not sure about "easy" for average user.
One of it looks like this:
1) Reflux your "A-oil" in double volume of ethyl formate (i.e 1:2 w/v) for at least 24h, then concentrate in to dryness under vacuum.
2) Reduce your N-formyl intermediate with LAH in THF under inert atmosphere (may take some days to go to completion).
