Temperature105 °C

Reaction Steps

75 mg of 1-(2-fluorobenzyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole-3-carboximidamide 1-2-4 (0.29 mmol, 1.0 eq.) and 44 mg morpholin-4-ylmalononitrile [0.29 mmol, 1.0 eq.; for preparation see: H. Gold and O. Bayer, Chem. Ber. 94, 2594 (1961)] were suspended in a small amount of DCM and the resulting suspension was evaporated to dryness. The residue was heated for one h at 105° C. The crude product was purified by flash chromatography yielding 86 mg (0.21 mmol, 72%) of analytically pure target compound.
