Reaktionsschritte
NaBH4 (15 g, 0.081 mol) was added in portions to ester 79 in ethanol (600 mL) at room temperature. After 4.5 hours water (˜200 mL) was carefully added to the reaction and the solution stirred at room temperature overnight. The resultant solid was removed by filtration and the filtrate concentrated to give alcohol 80 as an oil. 15.33 g, 81%. MS, m/z (relative intensity): 235 [M+H, 100%].
