Reaction Steps
To a solution of (R)-1-(5-(2H-tetrazol-5-yl)pentyl)-3-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)urea (12 mg, 0.019 mmol) in MeCN (115 μL) at rt was added K2CO3 (3.2 mg, 0.023 mmol) followed by MeI (1.5 μL, 0.023 mmol). The reaction mixture was heated to 80° C. overnight. The reaction mixture was quenched by addition of H2O and the aqueous layer was extracted with EtOAc (3×). The combined organic layers were concentrated and the residue was dissolved in MeOH and purified by preparative HPLC (Phenoma Luna AXIA 10A, C18, eluting with MeCN/H2O containing 0.1% TFA, monitoring at 220 nm) to provide (R)-1-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)-3-(5-(2-methyl-2H-tetrazol-5-yl)pentyl)urea (Example 260, 2 mg, 18% yield) as white solid. 1H NMR (500 MHz, CDCl3) ppm 7.17-7.08 (m, 5H), 6.99-6.85 (m, 5H), 6.67 (d, J=5 Hz, 2H), 5.98-5.75 (m, 1H), 4.23 (s, 3H), 3.82 (d, J=15 Hz, 1H), 3.68 (d, J=15 Hz, 1H), 3.10-3.07 (m, 2H), 2.85-2.82 (m, 2H), 1.77-1.71 (m, 2H), 1.46-1.40 (m, 2H), 1.32-1.26 (m, 2H); LC/MS: RT=3.218 min [M+H] 621.2 (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeCN/H2O over 4 minutes containing 0.1% NH4OAc; 4 mL/min, monitoring at 220 nm).
