Procedure

The product obtained in Step 4 (2 g) and sodium hydrosulfide (1.22 g) were dissolved in 35 ml of water, the solution was stirred at room temperature for 1.5 hours under a nitrogen stream, and the insoluble matters were filtered off. The filtrate was cooled to 0° C., its pH was lowered to 1-2 with 6N hydrochloric acid, the slurry was stirred at that temperature for 30 minutes, and the crystals thus formed were collected by filtration, washed with 30 ml of water and dried, affording 1.44 g of the objective compound.
