Procedure

The product obtained in Step 2 was added all at once at 0° C. to a solution of sodium hydrosulfide (20 g) in 450 ml of water with stirring under a nitrogen stream. The mixture was stirred at 0° C. for one hour, then for two hours at room temperature, and the resulting yellow solution was washed with 100 ml of ethyl acetate. The aqueous layer was acidified with concentrated hydrochloric acid to pH 2.0, and the formed crystals were collected by filtration and washed with 200 ml of ethanol, affording 18 g of the objective compound as faint yellow crystals.
