Reaction Steps

The product from step g) (963 mg, 3.58 mmol) in dichloroethane (18 ml) was treated with K2CO3 (1.97 g, 14.3 mmol) and Ace-Cl (1.54 ml, 14.3 mmol) at 80° C. for 16 hours. Next, the reaction mixture was filtered, concentrated and the residue was dissolved in anhydrous MeOH (25 ml) and stirred for 1 h at 22° C. The MeOH was concentrated and triturated with ether to give 467 mg (61%) of the subtitle compound. MS calculated for C10H13NS+H 180, observed 180.
