141774-61-0, tert-Butyl (piperidin-2-ylmethyl)carbamate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
HATU (157 mg, 0.413 mmol)was added to a stirred solution of 2-(l -ethyl- lH-indol-2-yl)-l – methyl-lH-benzo[d]imidazole-5-carboxylic acid (110 mg, 0.344 mmol)in DMF (2 mL)followed by DIPEA (0.072 mL, 0.413 mmol). After 30 min of stirring at rt, (+l-)-tert- butyl (piperidin-2-ylmethyl)carbamate (81 mg, 0.379 mmol)was added to the reaction mixtureand this was stirred for 2 h at rt. The solvent was removed under reduced pressure and water (10 mL) was added to the residue. A cream white precipitate was filtered off and rinsed with water (2 x 5 mL). The precipitate was dried in a vacuum oven for 2 h, affording 220 mg (113%) of a cream solid (the Boc-protected product). The Boc-protected product was then taken up in DCM (5 mL)and treated with TFA (1.5 mL, 19.47 mmol). After 30 min of stirring at rt the solvent was removed under reduced pressure and the dark purple residue was loaded in MeOH on a 2 g SCX column (previously conditioned with MeOH). The column was washed with MeOH (3CV) and eluted with methanolic ammonia (2N) (3 CV). The ammonia fractions were combined and evaporated under reduced pressure. The residue (189 mg) was loaded in DCM on a 10 g SNAP silica column and purified by SP4 flash chromatography, eluting with a 0-10% methanolic ammonia (2N) in DCM(10 CV). The appropriate fractions were combined and evaporated in vacuo to give (+/-)-(2- (aminom ethyl )piperi din- 1 -yl)(2-( 1 -ethyl- lH-indol-2-yl)- 1 -methyl- lH-benzo[d]imidazol-5- yl)methanone (11.4 mg, 0.027 mmol, 7.97 % yield)as a whitesolid.LCMS (Method B): Rt = 0.80min, MH+ = 416.2., 141774-61-0
As the paragraph descriping shows that 141774-61-0 is playing an increasingly important role.
