The Mosaic Law was passing away DURING the Last Supper. The passing away of the Old Covenant was COMPLETED when Jesus says so on the Cross.

Try again. Heb 8:13 Says the old covenant waxes old and is nigh onto passing away ... well after the cross. Elsewhere the time of it's passing is associated with heaven and earth passing away.

[Arthur McGowan]

You have the time frame completely wrong. Heb. 8:13 is referring to the time of the PROPHET (who has just been quoted at length), not the time of the author of Hebrews.

How could the Old Law conceivably be “close to passing away” when Hebrews was WRITTEN? It was GONE when the veil in the temple was torn open.

It helps to THINK, rather than just scouting around through Scripture looking for phrases that look like convenient weapons.
