Steps:

1; 2; 3; 4; 5 Example 1

MHT-OH 290 g (1 mol) and toluene 900 g were placed in a four-neck reaction flask, and the temperature was lowered to 15 ° C to start stirring. With hydrogen chloride, the reaction temperature does not exceed 30 ° C when ventilated. During the aeration process, TLC monitors the progress of the reaction. After the raw material is completely reacted, about 50 g of hydrogen chloride is introduced. The reaction solution was concentrated under reduced pressure at 40-65 ° C until almost no liquid, and 350 g of tert-butyl ether was added. Cool down to 10-25 °C. The mixture was stirred for 1 hour, filtered under reduced pressure, and the filter cake was washed once with 100 ml of petroleum ether. The infrared lamp is dried at 50-55 ° C, and the white crystal is 275 g. The yield was 89.1%, and the HPLC purity was 98% or more.
