Procedure

0.81 g (4.60 mmol) of 2,4-dichlorobenzaldehyde, 0.66 g (4.60 mmol) of Meldrum's acid and 25 mg (0.22 mmol) of D,L-proline were added to a solution of 0.95 g (4.38 mmol) of the compound from Example 11A in 36 ml of acetonitrile. The reaction mixture was stirred at RT overnight. It was concentrated to result in 3.10 g (97% of theory) of the title compound with a purity of 68% which were reacted without further purification.
