PROCEDURE

实验过程

To tert-butyl 3-((2R)-2-(3-amino-4-((dimethylamino)methyl)benzamido)-2-(2,9,9-trimethyl-3,5-dioxa-4-bora-tricyclo[6.1.1.02,6]dec-4-yl)ethyl)-2-methoxybenzoate from step 3 in Example 18 (130 mg, 0.22 mol) and (S)-2-(benzyloxycarbonylamino)-3-(tert-butoxycarbonylamino)propanoic acid (85 mg, 0.25 mol) in DCM/DMF (4 mL, 1/1) was added NMM (1.2 eq) followed by HATU (114 mg, 0.3 mol). The reaction mixture was stirred overnight at rt. Water was added and the aqueous phase extracted with EtOAc. The organic phase was washed with 1N HCl, sat. NaHCO3, brine, dried and concentrated in vacuo to afford the product (0.130 g) as a brown oil. ESI-MS m/z 926.1 (MH)+.
