61% With thionyl chloride; at -78 - 20℃; Neat [(5-FLUORO-2-METHOXY-PHENYL)-METHANOL] (19.587g, 1 equiv. ) was added [ TO NEAT SOC12 (42.2 ML, 4.6 EQUIV. ) AT-78C UNDER A NITROGEN ATMOSPHERE AND THE] solution was then allowed to warm to room temperature and stirred until evolution of gas had ceased. An equivalent volume of anhydrous toluene was added to the flask and the solution heated to [60C.] On cooling the reaction solution was poured onto ice water. The toluene layer was separated and dried (MgSO4) and the solvent removed under reduced pressure. The crude material was sublimed [(60-80C/0.] 05 [MBARR)] to give the title compound as a white solid (13.40 g, [61%). 1H No.] [(300MHZ,] CDCl3) : [No. ]3. 87 (s, 3H), 4.60 (s, 2H), 6.

61% With thionyl chloride; at -78 - 20℃; Neat (5-Fluoro-2-methoxy-phenyl) -methanol (19. 587G, 1 equiv. ) was added to NEAT SOC12 (42.2 ML, 4.6 EQUIV. ) AT-78C UNDER A NITROGEN ATMOSPHERE AND THE SOLUTION was then allowed to warm to room temperature and stirred until evolution of gas had ceased. An equivalent volume of anhydrous toluene was added to the flask and the solution heated to 60C. On cooling the reaction solution was poured onto ice water. The toluene layer was separated and dried (MgS04) and the solvent removed under reduced pressure. The crude material was sublimed (60-80C/0. 05 mBarr) to give the title compound as a white solid (13.40 g, 61 %). 1H NMR (300MHZ, CDC13): 6 3.87 (s, 3H), 4.60 (s, 2H), 6.79-7. 20 (m, 3H).
61% Neat (5-Fluoro-2-methoxy-phenyl) -methanol (19.587g, 1 equiv. ) was added to neat SOC12 (42.2 mL, 4.6 equiv. ) at-78C under a nitrogen atmosphere and the solution was then allowed to warm to room temperature and stirred until evolution of gas had ceased. An equivalent volume of anhydrous toluene was added to the flask and the solution heated to 60C. On cooling the reaction solution was poured onto ice water. The toluene layer was separated and dried (MGS04) and the solvent removed under reduced pressure. The crude material was sublimed (60-80C/0. 05 mBarr) to give the title compound as a white solid (13.40 g, 61%). IH NMR (300MHZ, CDC13) : 5 3.87 (s, 3H), 4.60 (s, 2H), 6.79-7. 20 (m, 3H).
