YieldReaction ConditionsOperation in experiment
7.7 g With N-ethyl-N,N-diisopropylamine In 1-methyl-pyrrolidin-2-one at 130℃; for 0.666667 h; Microwave irradiation Intermediate 22: 1,1-Dimethylethyl (2R)-2-[(7-chloropyrido[3,4-b]pyrazin-5-yl)amino]methyl}-4-morpholinecarboxylate
1,1-dimethylethyl (2R)-2-(aminomethyl)-4-morpholinecarboxylate (for preparation see: J. Medicinal Chemistry, 2009, 52 (15), 4810-4819) (6 g, 27.7 mmol) was dissolved in N-methyl-2-pyrrolidinone (NMP) (60 mL) and to this was added DIPEA (7.27 mL, 41.6 mmol) and 5,7-dichloropyrido[3,4-b]pyrazine (5.55 g, 27.7 mmol).
This was split between 4 large microwave vials and each was heated at 130° C. for 30 min.
They were monitored by LCMS and were given a further 10 min at 130° C.
The reaction mixtures were partitioned between ethyl acetate (700 ml) and diluted aqueous ammonium chloride (1 litre).
The aqueous was reextracted with ethyl acetate (300 ml) and the combined organics were washed with aqueous ammonium chloride (500 ml), dried over sodium sulfate and concentrated in vacuo to yield a crude brown oil.
It was dissolved in DCM and passed through silica (70 g) eluting with DCM (6*40 ml) then 5percent ethyl acetate in DCM (2*40 ml), 10percent ethyl acetate in DCM (5*40 ml) then 15percent ethyl acetate in DCM (2*40 ml) then 20percent ethyl acetate in DCM (2*40 ml). Appropriate fractions were combined and concentrated in vacuo to yield: N8231-100-2, orange-yellow slightly gummy solid, 7.7 g LCMS (Method B): Rt=1.17 min, MH+ 380
