Reaction Steps

To a solution of 2-(2-trifluoromethyl-biphenyl-4-yl)-2,3-dihydro-1H-isoindole-5-carbaldehyde (19 mg, 0.05 mmol) in 3 mL MeOH, β-alanine (8.7 mg, 0.1 mmol) and catalytic amount Et3N are added. The suspension is heated to 50° C. for 0.5 hours, followed by adding 2 mg of NaBH4. After pre-LC-MS, 8 mg of 3-{[2-(2-trifluoromethyl-biphenyl-4-yl)-2,3-dihydro-1H-isoindol-5-ylmethyl]-amino}-propionic acid is obtained as a white solid. MS m/z 441[M+1]+. 1H NMR (DMSO-d6): δ 7.08-7.26 (m, 9H), 6.80 (brs, 2H), 4.53 (s, 4H), 3.68 (s, 2H), 2.62 (t, 2H), 2.16 (t, 2H).
