Procedure

(RS)-3-(tert-Butyl-diphenyl-silanyloxy)-4-dibenzylamino-2-methyl-butan-2-ol (Example 95, step 2) was hydrogenated in EtOH with Pd(OH)2 for 16 hours at 60° C. The desired (RS)-4-amino-3-(tert-butyl-diphenyl-silanyloxy)-2-methyl-butan-2-ol (4.2 g, 92% yield) was obtained as a colorless oil, MS: m/e=358.2 (M+H+) and used in the next step without further purification.
