Reaction Steps
0.88 g (9 mmol) of ethylhydroxylamine are introduced into 20 ml of methanol. 0.62 g (4.5 mmol) of potassium carbonate are then added. 2.0 g (9 mmol) of 8-methylthiochroman-4-one-7-carboxylic acid are subsequently added. The reaction [sic] is stirred for 10 days at about 20° C. Work-up is carried out by adding water and 2N HCl. The precipitate which forms is filtered off with suction and dried.
