Its anion then displaces diisopropylamine, and the activated monomer couples with the free 5′-hydroxyl group of the support-bound chain to give a phosphite triester. BTT works in the same way as 1H-tetrazole, as an acid and as a nucleophile, but it is more acidic. It is used as a solution in anhydrous acetonitrile, typically at 0.25–0.3 M.\u003c\/p\u003e\n\u003cdiv style=\"margin:8px 0 18px 0;\"\u003e\n\u003cdiv
