The reaction temperature was 40℃ and the reaction time was 1.5h. The yield was 71.4%. In the second step, the optimum reaction conditions were determined by single factor method as follows: 100g of piperonyl propanaldehyde, 100g of methanol, 5g of 5% palladium-carbon catalyst, 300KPa absolute pressure of hydrogenation reactor, reaction temperature of 40℃, reaction time of 3h, yield of 93.1%Chemicalbook. The total yield of the two-step reaction was 66.5%. The structural products of the two-step reaction were characterized. Then we tried to synthesize the new jalal by one pot method, that is, the synthesis and hydrogenation of two steps were completed in a hydrogenation tank. The optimum reaction conditions were as follows: 100g of chloraldehyde, 100g of methanol, 40g of propanal, 5g of 5% palladium-carbon catalyst, 3g of potassium hydroxide, absolute pressure of 300KPa in hydrogenation reactor, reaction temperature of 40℃, reaction time of 3h, yield of 64.8%.
