YieldReaction ConditionsOperation in experiment
94.4% With methanesulfonic acid In N,N-dimethyl-formamide at 70℃; for 9 h; 5 g of compound 12 was added to 30 mL of DMF, 4.1 g of triethyl orthobutyrate and 0.5 g of methanesulfonic acid were added, and the mixture was heated with stirringTo 70 , the reaction 9h. The reaction was monitored by HPLC to control the remaining amount of raw materials to be 0.5percent or less of the initial amount. Ice bath cooling crystallization 2h, vacuum suction filtration. The wet product was dried at 80 ° C to give 6.2 g of white solid compound 2 as a white solid, yield 94.4percent.
