Participants

Reaction Steps

The subtitled compound (234 mg) was prepared using a similar method to that described in Preparation 3 Step iii) from 3-(3-(1-methyl-1H-pyrazol-4-yl)phenethoxy)propanoic acid [Example 2a, Step i)] and (R)—N-(2,2-dimethoxyethyl)hexan-2-amine [Preparation 13] and the reaction mixture was stirred for 2 h. The elution gradient used was 30-50% ethyl acetate in isohexane. 1H NMR (400 MHz, CDCl3) δ 7.75 (s, 1H), 7.62 (s, 1H), 7.36-7.24 (m, 3H), 7.11-7.05 (m, 1H), 4.69-4.63 and 4.41-4.37 (m, 1H), 4.38-4.31 and 3.85-3.76 (m, 1H), 3.94 (s, 3H), 3.85-3.76 (m, 2H), 3.74-3.65 (m, 2H), 3.43-3.37 (m, 6H), 3.33-3.25 (m, 1H), 3.22-3.14 (m, 1H), 2.94-2.85 (m, 2H), 2.80-2.57 (m, 2H), 1.59-1.12 (m, 9H), 0.93-0.85 (m, 3H); a ˜1:1 mixture of rotamers is observed.
