Procedure
0.87 g of the aldehyde of Stage A in 5 ml of tetrahydrofuran and 1 ml of water was cooled to 0° C. and 0.47 g of potassium borohydride were introduced. The mixture was stirred for 5 hours, poured into an aqueous sodium dihydrogenphosphate solution and extracted with isopropyl ether. The extract was dried and the solvent was evaporated to obtain 0.77 g of the expected product.
