N-tert-butyl-N-methylbenzamide

Conditions: temp:80.01; pressure:0.00; stir:

Procedure: In an argon filled glove box, a 5.0 mL wheaton microreactor was charged with [Ir(cod)(OMe)]2 (1.98 mg, 1.5 mol%), L1 ligand (2.1 mg, 3.5 mol%), B2pin2 (50.8 mg, 1.0 equiv.), KOtBu (1.0 mg, 4.5 mol%) and dry THF (1.0 mL). The reaction mixture was stirred for 2 minutes at room temperature. To this mixture, N-(tert-butyl)-N-methylbenzamide (38.3 mg, 0.2 mmol) was added. The microreactor was capped with a teflon pressure cap and placed into pre-heated aluminum block at 80 oC. The reaction mixture was stirred for 12 h. After completion (judged by GC/MS), THF was removed under reduced pressure and chromatographic separation with silica gel (15% ethyl acetate in hexane as eluent) gave the meta-borylated product 4c (41.2 mg, 65%) as white solid.

Procedure: Under nitrogen, 96.7 g (1.1 mol) of N-methyl-N-tertbutylamine and 111 g (1.1 mol) of triethylamine was dissolved in 1050 mL of anhydrous tetrahydrofuran (THF). The solution was cooled to 0° C. and treated with 140.6 g (1.0 mol) of benzoyl chloride. The reaction was allowed to slowly warm to ambient temperature and stir overnight. Filtration and subsequent concentration in vacuo of the filtrate gave the crude product which was purified by sublimation (65°, 0.2 torr) to give 184 g (96%) of colorless N-methyl-N-tertbutybenzamide: mp 80.5°-82.0° C.; NMR (CDCl3) δ1.52 (s, 9H), 2.87 (s, 3H), 7.34-7.40 (m, 3H), 7.40-7.46 (m, 2H). to slowly warm to ambient temperature Filtration and subsequent concentration in vacuo of the filtrate gave the crude product which was purified by sublimation (65°, 0.2 torr)
