To a THF (5 ml) solution of 6-(4-chlorophenyl)-1-methyl-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepin-5(6H)-one (20.0 mg, 0.06 mmol) was added BH3 THF complex (1 mL, 1M in THF) slowly. The resulting solution was stirred at room temperature for 2 h, concentrated. The residue was purified by Prep-TLC (pure EA) to give 6-(4-chlorophenyl)-1-methyl-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepine as an off-white solid (3.0 mg, 16%).
