YieldReaction ConditionsOperation in experiment
40.49% With palladium on activated charcoal; hydrogen; In tetrahydrofuran; methanol; for 3.5h; To a solution of 9-ethynyl-6,6-dimethyl-8-(4-morpholinopiperdin- l -yl)- l l -oxo-6, 1 1 - dihydro-5H-benzo[b]carbazole-3-carbonitrile (0.6 g) in methanol (28 ml) : THF (42 ml), Pd-C (0.36 g) was added and stirred in a hydrogenator under hydrogen gas pressure for 3.5 hours. The reaction mixture was filtered through Celite bed and the filtrate was concentrated under reduced pressure at 40 C. The resulting material was purified by column chromatography (dichloromethane:methanol) to give 0.245 g (40.49%) of Alectinib. XRPD pattern of Alectinib obtained after column chromatography is shown in Fig. 1 (Form A).
25% With palladium 10% on activated carbon; hydrogen; In tetrahydrofuran; methanol; at 20℃; for 2.0h; General procedure: To a solution of 14c (34.0 mg, 0.08 mmol) in MeOH/THF (1.6 mL/2.4 mL), 10% palladium on charcoal (20 mg, 60% w/w) was added at room temperature. After being stirred vigorously under hydrogen gas for 2 h at room temperature, the reaction mixturewas filtered through Celite. The filtrate was concentrated under reduced pressure. The residue was purified by flash column chromatography (CH2Cl2/MeOH) to yield 15c as a white solid (6.9 mg,19%).
