Procedure
1.0 ml (0.01 mol) tetrahydrofurfuryl alcohol are added to a mixture of 1.0 g (0.033 mol) sodium hydride (80%) in 10 ml dimethylformamide and after-stirred for 1 hour. Then, 2.95 g (0.01 mol) 6-chloro-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)-nicotinic acid, dissolved in 10 ml dimethylformamide, are added dropwise. The mixture is then stirred for 1 hour at 50°-60° C., cooled to room temperature, then 10 ml water is added, followed by acidifying with concentrated hydrochloric acid. The product is extracted with methylene chloride, the extract is dried across magnesium sulfate, filtered and compressed. After a certain period the product crystallizes from the obtained oil.
