2-chloro-N-cyclopentyl-5-nitro-N-[(1R)-1-(1,3,4-oxadiazol-2-yl)propyl]pyrimidin-4-amine (61.5 mg, 0.1743 mmol) and methyl 4-amino-3-methoxy benzoate (37.9 mg, 0.2092 mmol) in 4-methylpentan-2-ol (600 L) were treated with DIPEA (33.8 mg, 45.6 mL, 0.2614 mmol) and the reaction mixture stirred at 140° C. for 4 hours. The reaction mixture was concentrated in vacuo and the residue purified by column chromatography (50% EtOAc/Petrol) to give the sub-title compound as a brown oil (42 mg, 48%); 1H NMR (400.0 MHz, DMSO) d 0.75-0.89 (3H, m), 1.15-1.75 (8H, m), 2.24-2.34 (1H, m), 2.40-2.51 (1H, m), 2.61-2.72 (1H, m), 3.55-3.63 (1H, m), 3.84 (3H, s), 3.89 (3H, s), 7.44 (1H, s), 7.55-7.65 (2H, m), 7.75-8.03 (1H, br s), 8.12 (1H, s), 8.77 (1H, s); MS ES(+) 498.1.
