실험 절차

In 20 ml of DMF were dissolved 2.0 g (5.8 mmol) of 3,7-diformyl-10-p-tolylphenothiazine (2b) and 4.0 g (13.2 mmol) of diethyl diphenylmethylphosphonate (3a). Thereto was gradually added 1.5 g (13.4 mmol) of potassium t-butoxide. After the mixture was reacted overnight, 10 ml of methanol was added thereto. The crystals precipitated were taken out by filtration, dissolved in chloroform, purified by silica gel column chromatography (toluene), and then recrystallized from a chloroform/hexane mixed solvent to obtain 1.48 g of the target compound.
