Mode opératoire

A mixture of 7.46 g (41 mmole) of D-mannitol and 6.2 g (41 mmole) of xylitol is heated for 30 minutes to 80° C. with 67.5 g (227 mmole) of BEPDIB. After the readily volatile constituents have been distilled off in vacuo (10-3Torr), 11.6 g (96%) of bp. 108° C./10-3Torr and [α]D20 9.7 (c=6, CCl4) and 9.2 g (91%) of viscous residue are obtained.
