You might just want to keep it in the jar for the rest of the season instead of trying to plant it. I think you may have better luck keeping the tomatoes.

I had a smaller branch broken off and did the same thing, was able to pot it after it had grown new roots, and then planted it in the ground once it was established in the pot. It now has tomatoes on it - it happened earlier than yours has. Make sure you have cut the brown off at the base, if it's still there, and you will need to give it a lot of top support once potted because the top will be too big for the root system for some time. There are no guarantees but there's nothing to lose by trying.

Thanks you but will the plant die? Is there a chance?

Because of the size of it, it may be a difficult transition. Tomato plants can form what are called "adventitious roots" along the stem, so it will probably have some roots in about a week. Whether it will have enough roots to support the top enough for potting at this late stage in the year I don't know. If the base is brown you do need to cut that off so that the green can take up water. That it's wilting isn't a good sign, it needs to be in the shade and out of the wind.
sooby said:The part that is in the water doesn't look very healthy, did you cut the brown base off? At this point you might be better just saving the fruit that is on it and large enough that it will turn red off the plant.
