Procedure

A solution of 3.76 g (10 mmol) of the acid obtained in Example 18(b) was added dropwise to a suspension of 1.14 g of lithium aluminum hydride in 10 ml of tetrahydrofuran, and the mixture was maintained under stirring for 3 hours at room temperature. The reaction medium was neutralized at 0° C. by adding saturated ammonium chloride solution dropwise. The precipitate was filtered off, washed with hexane and dried to yield 3.13 g (86%) of the expected compound, melting at 113°-115° C.
