実験手順

0.68 g (4.41 mmol) of 4-chloro-2-methylbenzaldehyde, 0.64 g (4.41 mmol) of Meldrum's acid and 24.0 mg (0.21 mmol) of D,L-proline were added to a solution of 1.00 g of the compound from Example 11A with a purity of 82% (4.20 mmol) in 35 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 1N hydrochloric acid, saturated aqueous sodium bicarbonate solution and water, dried over magnesium sulfate, filtered and concentrated. 2.40 g of the title compound were obtained and were reacted without further purification.
