実験手順

1-(Benzo[d][1,3]dioxol-5-yl)-N-(2-tert-butylindolin-5-yl)cyclopropanecarboxamide (50 mg, 0.13 mmol) was dissolved in dichloroethane (0.20 mL) and 2,2-dimethyl-1,3-dioxan-5-one (0.20 mL). Trifluoroacetic acid was added (0.039 mL) and the resulting solution was allowed to stir for 20 minutes. Sodium triacetoxyborohydride was added (55 mg, 0.26 mmol) and the reaction mixture was stirred for 30 minutes. The crude reaction mixture was then evaporated to dryness, dissolved in N,N-dimethylformamide and purified by preparative HPLC using a gradient of 0-99% acetonitrile in water containing 0.05% trifluoroacetic acid.
