Reaktionsschritte

To a mixture of 2-methylpyrimidine-5-carbaldehyde (1.0 g, 8.2 mmol) and triisopropoxymethane (2.3 g, 12 mmol) in isopropanol (15 ml) was added methanesulfonic acid (0.079 g, 0.053 ml, 0.819 mmol). The reaction was stirred at room temperature for 23 hours. Potassium carbonate (1.132 g, 8.19 mmol) was added and the mixture was filtered and the solution was concentrated in vacuo. The crude mixture was purified by flash chromatography to yield 5-(diisopropoxymethyl)-2-methylpyrimidine (536 mg, 29%)
