Triethylamine → n-{2-[4-(3,5-Dichlorobenzyl)-3,5-diethyl-1h-pyrazol-1-yl]ethyl}-2,4-dioxo-1,2,3,4-tetrahydro-5-pyrimidinesulfonamide

Participants

Reaction Steps

A solution of the amine of Example 43 (6.5 mg, 20 μmol) and triethylamine (6 μl, 40 μmol) in dimethylformamide (250 μL) was treated with 2,4-dioxo-1,2,3,4-tetrahydro-5-pyrimidinesulfonyl chloride (J. Am. Chem. Soc., 1956, 78, 401) (0.8 mg, 4.0 μmol) and the mixture was shaken for 18 hours. The reaction mixture was filtered and the filtrate was purified by HPLC (Hypersil Thermoquest Luna C8 150×10 mm column; a gradient mobile phase was used, 10:90 (by volume)→95:5 (by volume) acetonitrile:(water, 95% by volume/trifluoroacetic acid, 0.1% by volume/acetonitrile 5%, by volume)).
