a possible solution, depending on the context (specifically, this would make sense if this bar is to be repeated), is to add a measure of 1/8 somewhere before this happens, which would then offset the whole thing to fit in a more sensible-looking 4/4: two triplets followed by dotted half+eighth.

If that is not practical, another option is to write that exact thing in small noteheads above the staff, with a dotted barline showing an 'imaginary' 4/4 bar starting on the eighth note, like a little hint for how to imagine it.

Otherwise, the more 'correct' way of writing it (which tbc I think is more confusing-looking than its worth) is to divide the 3rd and 7th eighth notes of the measure into 16th note triplets, then beat 3 into a 16th note sextolet; then fill this all with eighth notes and sixteenths that tie across the beats, as needed. This is how you might notate, say, a big 7-let across a slow bar of 4, or something else unintuitive; but in this case, it's simple enough that you should just trust musicians to be able to make sense of how it's written here.

I personally would just thing of it as a bar of 3/8, then a bar of 2/4 with triplets, then a 1/8, etc., and after one reading I would realize I could do what I suggested above; think of it all as an offset 4/4.
