Reaction Conditions:

with titanium tetrachloride in dichloromethane at 0 - 20;

Steps:

1.1 Step 1

will be (2 mmol, 356 mg) the anthracene dissolves in 10 ml dichloromethane in, lowering the temperature to 0 °C, plus (2 mmol, 230 mg) 1, 1 - dichloro methyl ether and 390 mg titanium tetrachloride, raising the temperature to room temperature, stirring 2 - 5 the H, add 20 ml saturated sodium bicarbonate, for 20 ml dichloromethane extraction to obtain the organic phase and drying, evaporating the solvent to obtain the intermediate pressure S1, namely 9 - [...]. Is the yellow solid, yield 95%.
