Dona, For problems like these, one uses what is called the "Jesuit" solution. For example one in no sense chooses to destroy the left over butyl lithium; instead one decides to synthesize the compound X and it just happens that one of the best ways to make X involves the consumption of that butyl lithium. So, following the procedures required by the local Chemical Hygiene Plan, one devises a series of written steps that describe the procedures by which one intends to make compound X. Et cetera.
