実験手順

To a solution of crude (1S,2R)-4′-(4-chlorophenyl)-2′,3′,9′-trimethylspiro[cyclopropane-1,6′-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine]-2-carbaldehyde (298 mg, 0.752 mmol) in t-BuOH (5 mL) was added 2-methylbut-2-ene (1055 mg, 15.04 mmol) and a pH 7 buffer solution (5 mL). Then sodium chlorite was added at rt, and the biphasic reaction was vigorously stirred for 3.5 h. When the starting material was entirely consumed, sat. aq. NH4Cl was added, and the product was extracted with DCM/MeOH (19:1) (repeated 3 times). The organic layers were combined, dried over Na2SO4, filtered and concentrated to dryness. The residue was used in the next step without purification. LRMS (M+H)+: 413 m/z.
