実験手順

The bromomethylketone of example 11 (39.6 mg, 0.078 mmol, 1 equiv.) was dissolved in DMSO (1 mL) and N-tertbutylthiourea (12.4 mg, 0.094 mmol, 1.2 equiv.) was added. The mixture was stirred for 2 h at room temperature. 10 N NaOH (24 μL) was added and after stirring for 4 h at room temperature, another portion of 10 N NaOH (24 μL) was added and the mixture stirred 24 h at room temperature to complete the hydrolysis. The reaction mixture was then neutralized by addition of TFA and the title product of example 12 isolated directly from the reaction mixture by preparative HPLC as a white amorphous TFA salt (21 mg).
