Participants

Reaction Conditions

Reaction Steps

5.1 g (30 mmol) of 5-hydroxy-2-nitrobenzyl alcohol were stirred with 2.5 g (18 mmol) of potassium carbonate and 25 ml of N,N-dimethylacetamide at 70°-80° C. for 30 minutes. After cooling to 20° C., 3.9 ml (36 mmol) of 1-butylbromide were added dropwise and the mixture was stirred at 90° C. for 2 hours. After cooling, the reaction mixture was concentrated in vacuo, the residue was treated with water and the pH was brought to 7 with 2N HCl. The oil obtained crystallizes after about 30 minutes; the product was filtered off with suction, washed with water and dried; 6 g, melting point 47°-49° C.
