The synthetic route is as follows., Computed Properties of C6H11N3
To a chilled solution of 4-isopropyl-1 H-pyrazol-5-amine (2.5 g, 20 mmol) in 20 ml DCM ethoxycarbonyl isothiocyanate (2.6 g, 20 mmol) dissolved in 10 ml DCM were added dropwise. The resulting suspension was further diluted with 30 ml DCM and stirred for 2 h. The product was collected, washed with DCM and dried. 2.0 g (7.8 mmol) of this raw material together with 3.2 g (23.4 mmol) were then refluxed in 15 ml MeCN for 2 h. After careful neutralization with acetic acid the solvent was removed in vacuo. The remaining solid was suspended in water. The product was collected, washed with water and dried to yield title compound (II) as colorless powder. 1 H-NMR (400MHz, d6-DMSO, 300K) delta 1 .14 (d, J = 6.8 Hz, 6H), 3.12 (h, J = 6.8 Hz, 1 H), 7.88 (s, 1 H), 12.60 (s, broad, 1 H), 13.34 (s, broad, 1 H); MS (ES) C8H10N4OS, requires 210.06, found 21 1 .3 (M+H)+.
