YieldReaction ConditionsOperation in experiment
35.1% With hydrogenchloride; sodium nitrite; In ethanol; water; at 0℃; for 0.5h; 3) 190g of intermediate II and 2.86L of hydrochloric acid (2M) were weighed in a 10L four-necked flask, and 61.04g of 0.96 L aqueous solution of sodium nitrite was added to the system at a controlled temperature of 0 C. The starting material II was added at 0 C and stirred for 0.5 hours, 3.78 L of ethanol was added and the pH was adjusted to 7-8 with sodium bicarbonate. After stirring at room temperature for 24 hours, suction filtration was performed. The filter cake was slurried with 4.2 L of water for 0.5 h. The filter cake was acidified and slurried with 4.2 L of concentrated hydrochloric acid for 0.5 h. After the solution was dissolved under reflux, the temperature was lowered to 0 C, and the mixture was continuously stirred for 2 hours, and then filtered by suction. After the solid was put into air drying at 55 C for 12 hours, 128.72 g of a dark red solid was obtained. The yield was 35.1% and the purity was 99.1%
