Reaction Steps
Tert-Butyl (2-hydroxyethyl)carbamate (8.88 g, 55.08 mmol) was added to a solution of NaH (55%, 55.08 mmol, washed twice with petroleum ether) in DMF (150 ml) at −10° C. and stirred for 10 mins. 2-Chloro-5-(trifluoromethyl)pyridine (10.0 g, 55.08 mmol) was added and the reaction mixture was stirred at rt for 3 days, heated to 100° C. and cooled to rt. The reaction mixture was evaporated, the residue was washed with isopropylether, and the solution was decanted from insoluble salts and concentrated. The residue was dissolved in EtOAc, washed twice with water, dried over MgSO4 and concentrated. Recrystallisation from isobutylethyl ether gave the title compound (6.2 g, 37%). 1H-NMR (500 MHz, CDCl3) δ 1.46 (s, 9H), 3.56 (br.m, 2H), 4.45 (t, 2H), 6.84 (d, 1H), 7.79 (dd, 1H), 8.44 (s, 1H.
