Reaction Steps

To a solution of 2-((1S,2S,4R)-bicyclo[2.2.1]heptan-2-ylamino)-5-(2-hydroxyethyl)-5-(2-methylallyl)thiazol-4(5H)-one (120 mg) in CH2Cl2 (3 mL) was added concentrated H2SO4 (200 uL). The resulting mixture was stirred for 16 h, then concentrated in vacuo. The residue was treated with sat'd NaH2PO4 and extracted with CH2Cl2. The organic layer was washed with sat'd NH4Cl, 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 solid. MS (ES+): 309 (M+H)+. The diastereomers were separated using standard HPLC methods described within this text.
