Pseudomonic acid (10.01 g, 20 mmole) was dissolved in a mixture of methanol/water (50 ml and 36 ml). Calcium oxide (0.78 g, 14 mmole) was added portionwise to the mixture and was stirred for 1 h. The solution was filtered, and the methanol was evaporated from the filtrate at reduced pressure to give a final volume of 30 ml. Water (20 ml) was added to the solution. Then the solution was freeze dried to obtain 9.11 grams of product.
