To a solution of [1(S)-(methoxy-methyl-carbamoyl)-2,2-dimethylpropyl]-carbamic acid-tert-butyl ester (1.686 g, 6.15 mmol) in dichloromethane (20 mL) at 0° C. was added trifluoroacetic acid (17 mL). The reaction was allowed to stand for 16 hours at <5° C. before the solvents were removed in vacuo to give a bright yellow oil. The residue was dissolved in methanol (30 mL) and was treated portionwise with Dowex 1X8-400 basic resin until pH 9. Filtration and removal of the solvents in vacuo gave the title compound as a pale yellow oil (990 mg, 92%). The material was used without further purification.
