Participants

Reaction Steps

A solution of 1,1-dimethylethyl {(2S,4R)-1-acetyl-6-[1-(2-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}ethyl)-1H-1,2,3-triazol-4-yl]-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl}carbamate (for a preparation see intermediate 46) (599 mg, 1.131 mmol) in dichloromethane (DCM) (20 mL) was treated with trifluoroacetic acid (TFA) (5.00 mL) and the resulting reaction mixture was stirred for 1 h at room temperature then concentrated in vacuovacuo. Purification of the residue on SP4 using a 50 G silica cartridge (gradient:0 to 12% MeOH in DCM) gave 2-{4-[(2S,4R)-1-acetyl-4-amino-2-methyl-1,2,3,4-tetrahydro-6-quinolinyl]-1H-1,2,3-triazol-1-yl}ethanol (396 mg, 0.885 mmol, 78% yield) as a yellow solid.
