Procedure

To a solution of 2-((1S,2S,4R)-bicyclo[2.2.1]heptan-2-ylamino)-5-methylthiazol-4(5H)-one (1.10 g, 5.0 mmol) in THF (5 ml) at −78° C. was added LDA (2.0 M, 10 ml). After 5 min, acetone was added, and the reaction mixture was stirred for 1 h at −78° C. The resulting reaction mixture was poured into a sat'd NaH2PO4, and extracted with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The crude residue was purified by flash chromatography (4:1; Hexane:EtOAc) to give the title compound as a white solid. MS (ES+): 283 (M+H)+. The diastereomers were separated using standard HPLC methods described within this text.
