Yield:1883-13-2 86%

Reaction Conditions:

with methanol;potassium hydroxide in hexane at 50 - 60; for 0.5 h;

Steps:

Saponification of Esters; General Procedure
General procedure: To a 50 mL round-bottomed flask fitted with a stir bar was addedhexane (5 mL) and the respective 3-hydroxymethyl ester (1 mmol).This mixture was heated to 50 °C at which point sat. KOH in MeOH (0.5 mL) was added. This led to the instant formation of a precipitate. The mixture was then stirred vigorously at 60 °C for 30 min, then removedfrom heat, and the solvents were evaporated under reducedpressure to provide the product as a potassium salt. This residue wasdissolved in distilled H2O (10 mL) and extracted with CHCl3 (3 × 10mL). The aqueous layer was collected and acidified with concd HCl topH <1. Et2O (20 mL) was added to the aqueous acidic solution and thissolution was stirred vigorously for 1 h. The organic and aqueous layerswere separated the aqueous layer was extracted with Et2O (2 × 20mL). The combined organic layers were dried (Na2SO4), filtered, and evaporated under reduced pressure to give the corresponding product,which was used without further purification (Table 2).
