benzyl pyrrolidine-1-carboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Pyrrolidine-1-carboxylic acid benzyl ester, (224 mg, 0.9 mmol) was combined with 376 mg (1.0 mmol) of HATU. This mixture was dissolved in 15 ml of DMF. To this solution was added DIEA (1.8 mmol, 0.3 mL). This solution was stirred at room temperature for 1.5 hours. To this solution was then added 4-pyridin-3-yl-thiazol-2-ylamine (100 mg, 0.56 mg). Reaction mixture was stirred at room temperature overnight and then purified using reverse phase HPLC. MS: 409.1 (M+H+); H1 NMR (DMSO-d6): δ(ppm) (HCl salt) 12.62 (s, 1H), 9.28 (s, 1H), 8.78 (s, 1H), 8.03 (m, 2H), 7.38 (m, 3H), 7.04 (d, 2H), 5.00 (m, 2H), 4.53 (m, 1H), 3.62 (m, 2H), 2.22 (m, 1H), 1.89 (m, 4H). Reaction mixture was stirred at room temperature overnight purified
