Participants

Reaction Steps

8.4 g (2.1 mmol) of N-[1-(4-diethoxymethylpyrimidin-5-yl)-2-methylpropyl]-N-methy4-fluorophenylacetamide was dissolved in 100 ml of acetone, and 13 ml of 6N hydrochloric acid was added and reacted at room temperature for 5 hours. After completion of the reaction, the reaction solution was concentrated, and an aqueous sodium hydrogencarbonate solution was added to alkaline, followed by extraction with ethyl acetate. The organic layer was washed with an aqueous citric acid solution, water and an aqueous sodium chloride solution, in this order, dried and concentrated, and the obtained oily product was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:5 to ethyl acetate) to obtain 5.3 g (yield: 77%) of N-[1-(4-formylpyrimidin-5-yl)-2-methylpropyl]-N-methyl-4-fluorophenylacetamide as colorless viscous liquid (nD20=1.5466).
