Reaction Steps
In analogy to example 45, step 1, 2-chloro-N-isobutyl-benzenesulfonamide (example 42, step 1) was reacted with 6-bromo-2-pyridinemethanol (CAS [33674-96-3]), triphenylphosphine and diethyl azodicarboxylate in tetrahydrofuran to give N-(6-bromo-pyridin-2-ylmethyl)-2-chloro-N-isobutyl-benzenesulfonamide as a colorless oil.
