Hydrochloric Acid → HCID 19004662, compound

Participants

Reaction Steps

5 g of potassium carbonate was added to a solution of 1.4 g of allyl trans-4-(4-acetoxy-3-methoxycinnamoyloxy)-1-methyl-1-cyclohexanecarboxylate (Example 12) in 70 ml of methanol. The resultant solution was stirred for 2 hours at room temperature. After reaction, 2N hydrochloric acid was added to the solution, acidifying the solution. The solution was extracted three times with 50 ml of ethyl acetate. The organic layer obtained was washed once with an aqueous sodium hydrogencarbonate solution and once with an aqueous sodium chloride solution, and was then dried over magnesium sulfate. The solvent was removed in vacuo, yielding 1.09 g of allyl trans-4-(4-hydroxy-3-methoxycinnamoyloxy)-1-methyl-1-cyclohexanecarboxylate (a compound of the present invention) as white crystal, which had the following physiochemical properties:
