Procedure
Following the procedure described in Example 42(b), 14 g of 2-t-butoxycarbonylamino-1-(2-furyl)ethanol [prepared as described in step (a) above] was treated with phosphorus pentachloride to afford 15 g of the title compound as crystals, melting at 75°-77° C. This substance was used for the next step without purification because it was decomposed by silica gel column chromatography.
