Reaction Steps

Next, a solution of dimethyl (1-diazo-2-oxopropyl)phosphonate (1.4 eq.) in MeOH (0.6 M) was treated at 0° C. with K2CO3 (2.4 eq.) and 2-(4-fluorophenyl)-2-methylpropanal (1.0 eq.). The reaction mixture was stirred for 1 hour, diluted with EtOAc, washed with water, dried (Na2SO4) and concentrated giving 1-fluoro-4-(2-methylbut-3-yn-2-yl)benzene: 1H NMR (600 MHz, CDCl3) δ 7.48-7.50 (m, 2 H), 6.97-7.00 (m, 2 H), 2.33 (s, 1 H), 1.57 (s, 6 H).
