1090 mg (3.5 mmol) Nα-(tert-butoxycarbonyl)-N-methoxy-N-methyl-L-phenylalanine-amide was dissolved in 20 mL 2-methyltetrahydrofuran and cooled to 0° C. Then 4.2 mL (4.2 mmol) of a 1M lithium aluminum hydride solution was added slowly to THF, and the reaction mixture was stirred for 30 min at 0° C. Next 5% aqueous potassium hydrogen sulfate solution was added cautiously. The batch was then diluted with water and extracted with MTBE. The organic phase was dried over magnesium sulfate and concentrated in vacuo, yielding 820 mg (94% of the theoretical) of the title compound.
