Hydrochloric Acid → 3-[5'-ethynyl-2'-(5-fluoro-2,3-dihydro-indole-1-carbonyl)-3,4,5,6-tetrahydro-2H-[1,4']-bipyridinyl-4-yl]-7-methoxy-1,3,4,5-tetrahydro-benzo[d][1,3]diazepin-2-one

Participants

Reaction Steps

86 μL (86 μmol) of a 1N tetrabutylammonium fluoride solution in THF were added to 35 mg (57 mol) 3-[2′-(5-fluoro-2,3-dihydro-indole-1-carbonyl)-5′-trimethylsilanyl-ethynyl-3,4,5,6-tetrahydro-2H-[1,4′]bipyridinyl-4-yl]-7-methoxy-1,3,4,5-tetrahydro-benzo[d][1,3]-diazepin-2-one in 1.5 mL THF and the mixture was stirred for 3 h at RT. Then the reaction mixture was combined with a 0.1 molar aqueous hydrochloric acid solution and the precipitate formed was suction filtered.
