Reaction Steps

2-((4-Ethoxyphenoxy)methyl)oxirane (0.06 g, 0.32 mmol) and 1-(1-(2-chlorobenzyl)-3,5-dimethyl-1H-pyrazol-4-yl)-N-methylmethanamine (0.10 g, 0.38 mmol) were dissolved in methanol (0.32 ml), warmed to 68° C. and stirred until the oxirane was consumed as observed by TLC. The solution was cooled to room temperature and the solvent removed under reduced pressure. The resulting oil was purified using flash column chromatography with 1:2:0.01 ethyl acetate:hexanes:triethylamine as the eluting solvent to yield 0.09 g (63%) of 1-(((1-(2-chlorobenzyl)-3,5-dimethyl-1H-pyrazol-4-yl)methyl)(methyl)amino)-3-(4-ethoxyphenoxy)propan-2-ol as a clear liquid. 1H NMR (500 MHz, CDCl3) δ 7.35 (dd, J=7.8, 1.2, 1H), 7.17 (td, J=7.7, 1.3, 1H), 7.12 (td, J=7.5, 1.2, 1H), 6.85-6.79 (m, 4H), 6.48 (dd, J=7.6, 0.9, 1H), 5.28 (s, 2H), 4.12-4.04 (m, 1H), 3.97 (q, J=7.0, 2H), 3.90 (d, J=4.9, 2H), 3.47 (d, J=13.2, 1H), 3.34-3.29 (m, 1H), 2.60 (dd, J=12.2, 9.7, 1H), 2.48 (dq, J=12.2, 3.9, 1H), 2.26 (s, 3H), 2.24 (s, 3H), 2.11 (s, 3H), 1.38 (t, J=9.1, 3H). 13C NMR (75 MHz, CDCl3) δ 153.47, 153.04, 148.04, 138.67, 135.31, 131.92, 129.43, 128.79, 127.58, 127.50, 115.63, 115.63, 115.53, 115.53, 113.71, 71.25, 66.37, 64.14, 59.51, 51.70, 50.28, 42.09, 15.13, 12.36, 9.82.
