The invention provides a novel synthesis process of Darunavir intermediate, N-tertbutyloxycarbonyl-L-phenylalanine is used as a raw material, esterification, condensation, reduction, hydrogenation and reduction amination, and other reactions are carried out for preparing the key intermediate of Darunavir: (2R,3S)-3-(tert-butyloxycarbonyl)amino-1-[(2-methyl propyl)amino]-4-phenyl-2-butanol. The new synthesis process of Darunavir intermediate has the advantages of mild reaction condition, simple operation, and high reaction selectivity and yield, and the process is suitable for industrial production.
