To a solution of mixture of compound 8 (1.0 g, 2.67 mmol) and PPh3 (1.4 g, 5.34 mmol) in CH2Cl2 (15 mL) was added NCS (1.07 g, 8.01 mmol) portionwise at 0° C. Then the resulting mixture was stirred at rt for 1 h and poured into a silica gel column and eluted with EtOAc-hexanes (1:4) using pressure. The collected right fractions were combined, concentrated, and co-evaporated with CH2Cl2 several times and used next step (1.0 g, 95%).
