Versuchsvorschrift

1.48 g (9.31 mmol) of 4-chloro-2-fluorobenzaldehyde, 1.34 g (9.31 mmol) of Meldrum's acid and 48.7 mg (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 70 ml of acetonitrile. The reaction mixture was stirred at RT overnight. It was concentrated, and the residue was taken up in ethyl acetate, washed with saturated aqueous sodium bicarbonate solution, water and saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered and concentrated. 3.60 g of the title compound were obtained and were reacted without further purification.
