Procedure

The product of step c) (5.2 g, 0.021 mol) was dissolved in dry pyridine (60 ml), placed under nitrogen and cooled with an ice-bath. Tosyl chloride (4.8 g, 0.025 mol) was dissolved in pyridine (30 ml) and added dropwise. The reaction was heated at 110°. After 5 hours another 2.2 g (0.011 mol) tosyl chloride was added in 20 ml pyridine at room temperature and the heating was continued overnight.
