The precipitate was collected by filtration and recrystallized from MeOH. In order to show generality of the procedure, the reaction was repeated with other benzaldehyde derivatives. The results are summarized in Table 1.Recyclibility of the catalyst: After evaporating of water the catalyst was filtered, washed with diethyl ether, dried at 130 °C for 1 h, and re-used in another reaction.
