Procedure

Intermediate 6, 3-(benzyloxy)-8,8-dimethyl-4-oxo-4,6,7,8-tetrahydropyrrolo[1,2-a]pyrimidine-2-carboxylic acid, (79 mg, 0.25 mmol) was placed together with O-(7-azobenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate, HATU, (114 mg, 0.3 mmol) in 2 mL DMF under N2 and stirred for 20 min. 4-(Dimethylamino)pyridine, DMAP, (100 mg, 0.8 mmol) and intermediate 3, 2-aminomethyl-5-fluoro-N-methylbenzamide trifluoroacetic acid salt (89 mg, 0.3 mmol) in 1 mL DMF were added and stirring continued for 20 min. The reaction mixture was concentrated, the residue dissolved in CH2Cl2 and washed with H2O. The CH2Cl2 layer was separated, dried (MgSO4), filtered and concentrated to give 118 mg of a the title compound as a solid (Yield=95%). 1H NMR (300 MHz, CDCl3) δ ppm: 8.31–8.46 (1 H, m) 7.24–7.46 (5 H, m) 6.95–7.15 (3 H, m) 6.88 (1 H, s) 5.23 (2 H, s) 4.48 (2 H, d, J=6.6 Hz) 3.95–4.10 (2 H, m) 2.93 (3 H, t, J=5.1 Hz) 2.00–2.16 (2 H, m) 1.34 (6 H, s); LC/MS m/z 479 (M+H).
