Procedure

1.34 g (8.46 mmol) of 4-chloro-3-fluorobenzaldehyde, 1.22 g (8.46 mmol) of Meldrum's acid and 0.05 g (0.42 mmol) of D,L-proline were added to a solution of 1.50 g (8.46 mmol) of the compound from Example 8A in 12 ml of acetonitrile. The reaction mixture was stirred at RT overnight. The precipitated solid was filtered off with suction, washed with acetonitrile and dried under high vacuum. 2.42 g (98% of theory) of the title compound were obtained.
