YieldReaction ConditionsOperation in experiment
53% Example 47 Production of Nalpha-tert-butoxycarbonyl-N?-methyl-L-histidine 1-(cyclohexyloxycarbonyloxy)ethyl ester Into a suspension of potassium carbonate (2.1 g, 14.9 mmol) in DMF (20 mL) was dropped a solution of Nalpha-tert-butoxycarbonyl-N?-methyl-L-histidine (2.0 g, 7.4 mmol) in DMF (20 mL) at 0 C. followed by stirring at room temperature for 0.5 hour. 1-Chloroethylcyclohexyl carbonate (1.8 g, 8.9 mmol) was dropped into the above mixture at 0 C. followed by stirring at room temperature for 20 hours. The reaction solution was poured over ice water, the mixture was extracted with ethyl acetate and the organic layer was dried over anhydrous sodium sulfate. The residue prepared by evaporation of the solvent therefrom in vacuo was purified by silica gel column chromatography (chloroform methanol=30:1) to give the title compound (1.7 g, 53%) as an oily substance. MS (EI) m/z: 440 (M+). 1H-NMR (DMSO-d6) delta: 1.32-1.44 (m, 15H), 1.62-1.64 (m, 2H), 1.81-1.83 (m, 2H), 2.89-2.94 (m, 2H), 3.31 (s, 3H), 3.52-3.53 (m, 3H), 4.21-4.23 (m, 1H), 4.54-4.56 (m, 1H), 6.62-6.66 (m, 2H), 7.39-7.41 (m, 1H), 7.48-7.49 (m, 1H).
