Reaction Conditions

Reaction Steps

A mixture of Intermediate 1-isopropyl-4-(2-(methylthio)pyrimidin-4-yl)-1H-pyrazol-3-amine (4.0 g, 16.0 mmol), isopentylnitrite (13.2 g, 112 mmol), and methylene iodide (30 mL) was heated at 100° C. for 3 h. Removal of the volatiles under vacuum provided a dark residue, which was purified by silica gel chromatography (2:1 hexane/ethyl acetate eluant) to afford the title compound as a solid; MS m/z: 361.1 (M+1).
