Acetonitrile → N-Cyclopropylmethyl-2-methyl-N'-(5-methyl-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin 7-yl)-malonamide

Participants

Reaction Steps

2-Methyl-N-(5-methyl-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-yl)-malonamic acid (20 mg, 0.059 mmol) and cyclopropylmethylamine (5 mg, 0.059 mmol) were placed in a disposable polypropylene tube and dissolved in DMF (2 ml). TPTU (2-(2-pyridon-1-yl)-1,1,3,3-tetramethyl uronium tetrafluoroborate, 19 mg, 0.065 mmol) was added, and the mixture was shaken overnight at r.t. The title compound, MS: m/e=392.2 (M+H+), was isolated from the reaction mixture by automated, preparative HPLC (YMC CombiPrep C18 column 50×20 mm, solvent gradient 5–95% CH3CN in 0.1% TFA(aq) over 6.0 min, λ=230 nm, flow rate 40 ml/min).
