YieldReaction ConditionsOperation in experiment
94.5% With hydrogen In water; butan-1-ol at 20℃; for 4 h; The compound (II) (R is p-nitrobenzyl) (15.0 g, 29.Ommo 1) was added 200 mL of n-butanol, 200 mL of water, stirred to dissolve, and 8.00 g of Raney Ni was added and hydrogenated at 20 ° C under 2.0 MPa hydrogen pressure for 4 h. The filter cake was washed with 15 mL of water The filtrate was adjusted to pH 6.5 with 4-dimethylaminopyridine and then washed with 150 mL of ethyl acetate. After cooling to 0 ° C, 700 mL of acetone was added dropwise, stirred for 10 min and then 700 mL of acetone was added dropwise, stirred for 1 h, To give telbemidine as a white solid 12.5 g, yield 94.5percent, purity 99.6percent.
89.3% With 0.5% Pd/C; hydrogen; sodium hydrogencarbonate In water; butan-1-ol at 25 - 30℃; for 3 h; The 229.2 g of the intermediate I obtained in Example 2 was successively mixed with 27.4 g of the volume of n-butanol aqueous solution (3: 1 volume of n-butanol and water), 27.4 g of palladium-carbon catalyst (0.5percent palladium), and 330.0 g of sodium bicarbonate. The reaction was carried out for 3 hours at a hydrogen pressure of 1MPa, temperature 25 to 30 ° C and a rotation speed of 500 r / min. After the completion of the reaction, the suction filtration was carried out and the filtrate pH was adjusted to 5.5 with 4mo 1/1 hydrochloric acid to give an aqueous phase and n-butanol phase; Cooling to 7 to 8 ° C, while stirring the aqueous phase slowly added 5 times its volume of acetone, the solution crystallization, filtration, drying was carried out to obtain the intermediate II 151.3g, the calculated yield was 89.3percent and the purity was 99.5percent.
