The reaction mixture was filtered. The filtrate was concentrated, diluted with dichlormethane, dried over MgSO4, and concentrated. The residue was purified on silica gel (eluting with 0 to 5% MeOH in dichloromethane) to give the desired product. (0.63 g, 70%). LCMS calculated for C15H19N4S (M+H)+: m/z=287.1. Found: 287.1.
