Reaction Steps

A mixture of phenylmethyl[(4-{(2S,4R)-1-acetyl-4-[(5-fluoro-2-pyridinyl)amino]-2-methyl-1,2,3,4-tetrahydro-6-quinolinyl}phenyl)methyl]methylcarbamate (for a preparation see intermediate 79) (55 mg, 0.100 mmol) and palladium (10% w/w on charcoal, 50% wet, 6.35 mg, 0.060 mmol) in ethanol (9 mL) was stirred under hydrogen (1 bar) at room temperature for 17 h then filtered through celite. The insoluble material was rinsed with ethanol (20 mL) and the combined filtrate and washings were concentrated in vacuo. Purification of the residue with MDAP (modifier: ammonium bicarbonate) gave a white solid which was dissolved in MeOH (0.4 mL), then treated with HCl (1.25M in MeOH, 38.3 μL, 0.0478 mmol). The resulting mixture was concentrated in vacuo to give (2S,4R)-1-acetyl-N-(5-fluoro-2-pyridinyl)-2-methyl-6-{4-[(methylamino)methyl]phenyl}-1,2,3,4-tetrahydro-4-quinolinamine hydrochloride (23 mg, 48%) as a pale yellow solid.
