To a solution of 2-triisopropylsilanyloxy-propane-1,3-diamine (Step P10) (27.8 g, 113 mmol) in MeOH (450 mL) was added S,S-dimethyl carbonodithioate (17.7 mL, 169 mmol) and the mixture was stirred at 60° C. for 20 h. The reaction mixture was concentrated. The residue was purified by flash chromatography(CH2Cl2/MeOH, 100:0→5:1) to afford the title compound. ESI-MS: [M+H]+273.3 (LC-MS 1-flow injection).
