You will probably want to use self-leveling polyurethane caulk. It is important to fill the gap to within 3/8" of the surface first. If the caulking is thicker than 3/8" it will not flex sufficiently and will not hold. A foam backer rod is generally used to fill the gap by compressing it and pushing it into the gap leaving 3/8" - 1/4" below the surface for the caulk. If a backer rod is not available you could fill the gap with sand first to the proper depth.

The sides of the gap (against the brick and concrete should be clean and free of dirt.

The self-leveling caulk is thin and will flow out to level itself. The backer rod will hold the caulking to the proper depth keeping it from getting too thick.

Check it every 30-60 minutes and fill in any areas that are too low. The caulk will flow down filling all voids and it will continue to do so until it begins to thicken.

If the joint you are filling is on a slope you will need to go slow or the caulk will run downhill and out of the gap.

Thanks for response. One question, will the polyurethane cauls adhere to the concrete ?
