Reaction Steps

The product from step f) (409 mg, 1.52 mmol) in dichloroethane (8 ml) was treated with K2CO3 (839 mg, 6.08 mmol) and Ace-Cl (658 μl, 6.08 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 hour at 22° C. The MeOH was concentrated and triturated with ether producing to give 215 mg (66%) of the subtitle compound as its HCl salt. MS calculated for C10H13NS+H 180, observed 180.
