Yield:95233-18-4 85%
Reaction Conditions:
with sulfuric acid at 15 - 16; for 0.333333 h;
Steps:
1
Cis-2-[4-(4-chlorophenyl)cyclohexyl]-3 -hydroxy- 1,4-naphthoquinone (1 g, 2.7 mmol) was stirred in 8 ml concentrated H2SO4 at 15-16°C for 20 minutes. The reaction mixture was slowly poured into 30 g ice and further stirred for 20 minutes. The obtained solid was filtered and washed with water until the pH of the filtrate becomes in the range of 4 to 5. The resulting solid is dried at 50-55°C for 6 hours to yield 0.85 g of trans-2-[4-(4- chlorophenyl)cyclohexyl]-3-hydroxy-l,4-naphthoquinone (85% yield, 95.5 % purity).
