Reaction Steps

To a mixture of 4,4-dimethyl-1-oxa-7-azaspiro[4.4]nonan-2-one hydrochloride (20.3 mg, 0.0000988 mol) and 1-{4-[4-(tert-butoxycarbonyl)piperazin-1-yl]-2-fluorophenyl}cyclopropanecarboxylic acid (36.0 mg, 0.0000988 mol) in N,N-dimethylformamide (0.30 mL, 0.0039 mol) was added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (48.1 mg, 0.000109 mol) followed by N,N-diisopropylethylamine (0.0206 mL, 0.000118 mol). After stirring at rt for 1 h, the reaction mixture was quenched with water and extracted with EtOAc. The organic layers were combined, washed with brine, and dried. The crude residue was used directly in the next step without further purification. LCMS (M+H) 516.3. (M+Na) 538.3.
