Reaction Steps

[3-(4′-{(5S)-5-[(Acetylamino)methyl]-2-oxo-1,3-oxazolidin-3-yl}-1,1′-biphenyl-4-yl)-4,5-dihydroisoxazol-5-yl]methyl di-tert-butyl phosphate (95 mg, 0.16 mmol) was dissolved in dichloromethane (1 ml) and trifluoroacetic acid (0.1 ml) was added. The solution was stirred for 1 h at ambient temperature, then concentrated in vacuo. Dichloromethane was added and the volatiles were removed in vacuo. This was repeated twice with dichloromethane and five times with diethyl ether. A pale yellow solid was obtained (78 mg) corresponding to the desired product.
