Procedure

To a solution of tert-butyl [2-({(1R)-3-methyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butyl}amino)-2-oxoethyl]carbamate (2.5 g, 5.9 mmol) in DCM (15 mL) was added 4M HCl in dioxane (5.9 mL The reaction mixture was allowed to stir for 2 h and concentrated to give 2-amino-N-{(1R)-3-methyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butyl}acetamide which was used in the next step without purification.
