実験手順

A mixture comprising tert-butyl (4R)-7,10,10,11,11-pentamethyl-4-(2-methyl-1-oxo-4-phenyl-2,7-diazaspiro[4.5]decane-7-carbonyl)-6-oxo-1-phenyl-2,9-dioxa-5-aza-10-siladodecan-7-ylcarbamate (Intermediate from step 4) (140 mg, 0.190 mmol) and 2M HCl in Et2O (2.9 mL, 5.70 mmol) was treated with water (300 mg, 16.65 mmol) dropwise and stirred at room temperature for 2 hours. The reaction mixture was concentrated in vacuo. The resulting crude was dried in a vacuum oven for 24 hours at 50° C. to afford the title compound. No purification was performed on the title compound.
