실험 절차

Freshly dried manganese dioxide (3.3 g) was added to a solution of 2-amino-5-iodo-3-methylbenzyl alcohol (2.0 g) in dichloromethane (50 cm3) under nitrogen and the mixture was stirred for 3 days at room temperature. The mixture was filtered, the filtrate evaporated to dryness, and the solid residue was chromatographed on silica (Merck "MK 60.9385" [Trade Mark]) eluting with dichloromethane. Combination and evaporation of appropriate fractions afforded the title compound, m.p. 134° (1.6 g).
