Reaction Steps

To a stirred solution of 3-isopropyl-1-methylcyclopentanecarboxylic acid (89 mg, 0.52 mmol) and 1-(3-(trifluoromethyl)pyridin-2-yl)piperazine (242 mg, 1.04 mmol) in N,N-dimethylformamide (1 mL) was added benzotriazole-1 yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (700 mg, 1.56 mmol). The reaction was heated in a microwave at 150° C. for 5 minutes. The reaction mixture was purified with HPLC to yield 1-[(3-isopropyl-1-methylcyclopentyl)carbonyl]-4-[3-(trifluoromethyl)pyridin-2-yl]piperazine in 42% yield (83.3 mg) as off-white solid.
