Reaction Steps

Cis(±)methyl 2-chloro-6-(4-{[(4-chloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)pyrimidine-4-carboxylate (Example 23; 0.12 g, 0.27 mmol) was dissolved in 0.5 M sodium methoxide in MeOH (5.4 ml, 2.7 mmol) and heated in the microwave for 1.5 h at 85° C. The reaction mixture was acidified with 1N HCl and the product was extracted with EtOAc, dried with MgSO4 and concentrated to a solid which was purified by reverse phase chromatography (gradient elution from 20-50% CH3CN in water with 0.5% TFA). Freeze drying yielded product as a white solid. MS (ES) MH+: 424 for C18H22ClN5O5; NMR: 1.62 (s, 1H), 1.75 (s, 1H), 2.14 (s, 3H), 3.26 (s, 3H), 3.53 (m, 3H), 3.87 (s, 3H), 4.22 (s, 2H), 6.88 (d, J=2.64 Hz, 1H), 7.07 (s, 1H), 7.66 (d, J=7.91 Hz, 1H), 11.63 (s, 1H).
