1001180-21-7, (R)-tert-Butyl 4-(5-methyl-7-oxo-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 40; 2-(4-chlorophenyl)-l-(‘4-((5R)-7-hydroxy-5,7-diniethyl-6,7-dihvdro-5H-cvclopenta[dlpyrimidin-4- vDpiperazin- 1 -ylV S-fisopropylamino’propan- 1 -one; Step 1 :; A solution of (R)-tert-butyl 4-(5-methyl-7-oxo-6,7-dihydro-5H- cyclopenta[d]pyrimidin-4-yl)piperazine-l-carboxylate (40 nig, 0.120 mmol) in THF (4 niL) was added to a 1.5M solution of methyllithium in diethyl ether (0.088 mL, 0.132 mmol) at -780C. The resulting mixture was stirred at -78C for 1 hour and quenched by saturated aqueous NH4Cl. The aqueous layer was extracted with EtOAc (2 X). The organic layer was dried (MgSO^ and concentrated. The residue was purified by a silica catridge (5.0 g) eluted by EtOAc to give tert-butyl 4-((5R)-7-hydroxy-5,7-dimethyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazine- 1-carboxylate as an off-white solid (29 mg, 69%). LCMS (APCI+) [M-Boc+H]+ 349.1; Rt: 2.49 min.
1001180-21-7, The synthetic route of 1001180-21-7 has been constantly updated, and we look forward to future research findings.
