Steps:
General Procedure for the Preparation of 2-5c
General procedure: Resorcinol (1.35 g, 12.250 mmol) wasadded to a reaction flask containing 2-5b and 70% H2SO4 (30 mL) in the ice bath. After 30min, the ice bath was removed and the reaction continued at room temperature. After thereaction finished, the solution was slowly added into ice water (300 mL) and stirred for 30min to precipitate a large number of solids. After extraction, filtration, and drying, compounds2-5c were obtained.
