The title compound was synthesized according to the procedure described for Example 9 using sodium tert-butoxide (48 mg, 0.5 mmol), methyl 2-oxo-5-indolinecarboxylate (21 mg, 0.11 mmol) and 4-chloro-5,6,7,8-tetrahydroquinazoline solution (0.1 mL, 1 M in N-methylpyrrolidinone, corresponding to 17 mg, 0.1 mmol; described in: Budesinsky Z., Roubinek F. Collect. Czech. Chem. Commun., 1964, 29, 2341). The crude oil was purified on SCX-column pre-rinsed with methanol using ethyl acetate, methylene chloride, methylene chloride/methanol 1:1, and methanol/ammonia (2 M, aq) as elution solvents.
