To a solution of tert-butyl [(2R)-2-hydroxypropyl]carbamate (2.7 g) in CH2Cl2 (41 ml) were added N,N,N′,N′-tetramethylnaphthalene-1,8-diamine (3.63 g) and trimethyloxonium tetrafluoroborate (2.51 g), and the whole was stirred for 3 hours at room temperature. Water was added to the mixture, and the whole was extracted with EtOAc, and the extract was washed with water and brine and dried over MgSO4. Concentration under reduced pressure gave tert-butyl [(2R)-2-methoxypropyl]carbamate (2.73 g).
