Reaction Conditions

Reaction Steps

Sodium cyanate (0.64 g, 9.8 mmol) in water (13 ml) was added dropwise to a stirred solution of amine 3 (2 g, 4.9 mmol) in water (63 ml) and 1M HCl (9.8 ml) at 80° C. After stirring for 3 h at 80° C. the mixture was cooled and basified with 2M NaOH. The mixture was extracted with CH2Cl2 until no more product remained in the organic phase. The organic phases were combined, dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by column chromatography [dichloromethane/methanol (97:3)] and the product triturated with ether to afford the title compound (1.0 g, 45%) as a pale yellow solid.
