実験手順

To a cooled solution of (2R,5R)-4-[2-(6-chloro-3,3-dimethyl-2,3-dihydro-indol-1-yl)-2-oxo-ethyl]-5-hydroxymethyl-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (100 mg, 0.22 mmol) in DMF (1.1 mL) at 0° C. (ice bath) was added sodium hydride (60%, 10 mg, 0.24 mmol). After stirring for 1 h, methyl iodide (15 μL, 0.24 mmol) was added and the reaction stirred for 30 mins. Reaction was allowed to warm gently to ambient temperature over 18 h. The solvent was removed in vacuo and residue was purified by column chromatography on silica gel (gradient elution, 0-100% EtOAc/petrol), to give the title compound (20 mg, 19%) as a colourless oil. 1H NMR (Me-d3-OD): 8.14 (1H, s), 7.27-7.13 (1H, m), 7.09 (1H, dd), 4.19 (1H, dd), 4.13-3.84 (3H, m), 3.78-3.44 (3H, m), 3.44-3.38 (1H, m), 3.36 (3H, s), 3.29 (1H, d), 3.07-2.94 (1H, m), 2.94-2.81 (1H, m), 2.66 (1H, dd), 1.48 (9H, s), 1.37 (6H, s), 1.34-1.20 (3H, m).
