Procedure

N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (20 mg, 0.052 mmol) was added to a solution of 2-amino-4-(4-methylpiperazin-1-yl)quinazoline-7-carboxylic acid (10 mg, 0.03 mmol) in N,N-dimethylformamide (2 mL) and N,N-diisopropylethylamine (12 uL, 0.070 mmol). The reaction was stirred for 10 min, and the methyl (2S)-2-amino-3-(4-isopropoxyphenyl)propanoate (16 mg, 0.070 mmol) was added. The reaction mixture was stirred for 2 h. at r.t. and was purified by RP-HPLC (pH=2) to afford the desired product (6 mg, 30%) as a white solid TFA salt. Analytical LCMS (M+H)+: m/z=507.0.
