Some context on where exactly you are in your LP would help, as well as starting and current weights.
But in my benevolence, I will answer despite your lazy lack of context, cause I feel bad for a guy who can't straighten out his arms (low blow?): just do a bunch of sub-maximal sets of chins while you're resting between the warm-up and work sets of your cleans and you'll be fine. Not a super-set; do the cleans, rest a bit, do the chins, rest as needed, do the next set of cleans. How many sets and reps you should do depends greatly on your max set of bodyweight chins, but start small with a few very submax sets, add a set each workout, and when you're doing a set between every warm-up and work set, start to add a rep to some of the sets, then a rep to all the sets. You'll probably actually be doing chins on a dedicated day before you even reach that point.
