Procedure
The product of EXAMPLE 14, Step 2 (1.0 g, 2.3 mmol) and Lawesson's Reagent (0.50 g, 1.3 mmol) are stirred in Toluene (20 mL) at reflux for 2 hours. Solvent is removed by evaporation and the residue is chromatographed on silica gel using 0-4% MeOH/CH2Cl2 eluant. The title compound is isolated as a white solid 1.0 g (97%); HRMS (FAB) calcd for C24H27N3O4S+H1 454.1800, found 454.1813.
