반응 단계
A 22.2 g. portion of 2-methylanthraquinone is reduced with 10 g. of zinc and 200 ml. of 20% sodium hydroxide in 40 ml. of ethanol, then alkylated with 50 ml. of 2-chloroethyl-p-toluene sulfonate as described in Example 1. The crude product is taken up in methylene chloride, filtered, dried over magnesium sulfate and concentrated to dryness. Recrystallization from 100 ml. of propanol gives 0.7 g. of the desired intermediate as a yellow solid, m.p. 82°-85° C.
