Reaction Steps

The product obtained in Step 2 (24 g) was added all at once, under a nitrogen stream, to a solution of 23 g sodium hydrosulfide in 600 ml of water, the mixture was stirred at room temperature for two hours, and the insoluble matters were filtered off. The filtrate was acidified to pH 2.0 with concentrated hydrochloric acid, and the crystals thus formed were collected by filtration, washed twice with 40 ml of water and dried, affording 22 g of the objective compound as yellow crystals.
