Versuchsvorschrift
Sodium hydrosulphide (0.252 g) was added to the product from example 4 step (i) (11.0 g) in dry DMF (10 ml) and stirred at RT for 2 h. The mixture was diluted with 2M sodium hydroxide solution and extracted with diethylether. The aqueous layer was acidified with 2M hydrochloric acid, extracted with ethyl acetate, dried and evaporated under reduced pressure, crude yield 1.60 g.
