Ethyl 2-(pyrazol-4-ylamino)cyclohexene-1-carboxylate (8.5 g, 0.036 mole) was added rapidly to refluxing Dowtherm A (250 ml) under nitrogen and the mixture heated under reflux for a further 15 minutes, before allowing to cool to room temperature. The mixture was diluted with 60°-80° petroleum ether (200 ml) and the solid then filtered off, washed well with petroleum ether and then ethanol, before drying under vacuum to give the title compound as a white solid (6.26 g, 92%), m.p. >325° C. Found: C, 63.20; H, 5.85; N, 22.20% C10H11N3O requires C, 63.50; H, 5.85; N, 22.20%
