1,1-dimethylethyl [2-({[4-(2-methyl-2-oxido-1,2-oxaphospholan-5-yl)phenyl]carbonyl}amino)-4-(2-thienyl)phenyl]carbamate (95 mg, 0.185 mmol) was taken up in DCM (5 mL)/TFA (2 mL). After 3 hours, saturated NaHCO3 was added and the products extracted into EtOAc (×2). The combined organic extracts were washed with brine, dried over MgSO4 and concentrated in vacuo to give N-[2-amino-5-(2-thienyl)phenyl]-4-(2-methyl-2-oxido-1,2-oxaphospholan-5-yl)benzamide as a yellow solid. The title compound was obtained as a 1:1 mixture of diastereosiomers. MS: cal'd 413 (MH+), exp 413 (MH+).
