Reaction Conditions

Reaction Steps

A 0° C. solution of 4.5 g of product from Example 333 in 77.8 ml of diethyl ether and 25.5 ml of water is treated with 2.58 g of solid sodium bicarbonate followed by 7.6 g of iodine. The reaction is stirred for 3 hours at 0° C. then at room temperature overnight. The mixture is cooled to 0° C. and sodium sulfite is added until the reaction is colorless. The solution is extracted with diethyl ether, dried and concentrated in vacuo to give 7.0 g of an oil. The oil is purified by chromatography (Silica gel: 5% diethyl ether/hexane) to give 2.8 g of Isomer A and 1.86 g of Isomer B. Isomer A:
