Reaction Conditions:
with tert.-butylnitrite in benzyl alcohol at 20; for 30 h;Inert atmosphere;
Steps:
18 Example 18-21:
General procedure: The reaction substrate (0.3 mmol) was added to the reaction vessel.Benzyl alcohol (2mL) and tert-butyl nitrite (1.5equiv),Pumping the reaction vessel - nitrogen-filled operation for 3 consecutive times, reacting at room temperature, after the reaction is over,Diluted with ethyl acetate, concentrated under reduced pressure, and the concentrate was separated by column chromatography(wherein silica gel is 300-400 mesh silica gel), the ratio of petroleum ether to ethyl acetate isThe 4:1 mixture was used as an eluent, and the eluate was collected, and the solution was spun off to obtain a product.
