Diisopropylethylamine → HCID 86680552, compound

Participants

Reaction Steps

(S)-1-Azido-3-(2,4-dichlorophenyl)propan-2-amine (33 mg, 0.134 mmol) was added to a solution of (R)-5-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)thiophene-2-carboxylic acid (35 mg, 0.134 mmol) in DCM (0.7 mL). HBTU (56 mg, 0.148 mmol) was added, followed by DIPEA (0.23 mL, 1.34 mmol). The reaction mixture was stirred at room temperature for 1 hour. LC-MS of the reaction mixture showed no more starting material. The solvent was removed, and the resulting residue was purified on silica gel (0%-50% EtOAc/hexanes) gradient elution to yield N-((S)-1-azido-3-(2,4-dichlorophenyl)propan-2-yl)-5-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)thiophene-2-carboxamide as an oil (59 mg, 90%). m/z 486 (MH+).
