Thank you all for your help. I came accross a paper which cites another paper stating that bedaquiline is synthesised in five steps from 3-phenylpropionic acid and para-bromoaniline as the starting materials. I am interested in the quantities required as well as the full procedure for this five step process as I do not have access to the original paper whose reference is below:
