The solvent was removed in vacuo and the crude mixture filtered through silica gel using CH2Cl2. The solvent was removed in vacuo and the crude material (4.2 g) diluted with 50 mL of acetonitrile, treated with 4 mL of phosphorous oxychloride (POCl3), and the reaction mixture was heated to 80 C. for three hours. Additional POCl3 was added during this time to drive the reaction to completion. The solvent was concentrated in vacuo, diluted with EtOAc, washed with aqueous sodium bicarbonate and brine, dried over MgSO4, filtered and concentrated under vacuum. The residue was subjected to silica gel chromatography eluted with 10-30% ethyl acetate in hexanes to afford N-[(1R)-1-(4-bromophenyl)ethyl]-4-chloro-3-nitropyridin-2-amine with a mass ion (ES+) of 338.0 for M+H+(Br79).

Yield	Reaction Conditions	Operation in experiment
	With N-ethyl-N,N-diisopropylamine; In 1,1-dichloroethane; N,N-dimethyl-formamide; at 20℃; for 1h;	To a solution of <strong>[629655-23-8]2-chloro-3-nitropyridin-4-ol</strong> (0.722 g, 4.14 mmol) in 20 mL of dichloroethane and 0.5 mL DMF, was added DIEA (2.20 mL, 12.4 mmol) followed by chloro(methoxy)methane (0.63 mL, 8.28 mmol). After 1.0 h at ambient temperature, the reaction was concentrated and redisolved in 150 mL DCM. The DCM solution was washed with 100 mL of saturated sodium bicarbonate solution, 100 mL water and 100 mL of brine, respectively. The organics were dried and concentrated to afford the title compound as a white solid: 1H NMR (CDCl3) delta3.47 (s, 3H), 5.37 (s, 2H), 6.58-6.60 (d, 1H, 7.9 Hz), 7.54-7.57 (d, 1H, 7.9 Hz). MS: MH+=219.0

Yield	Reaction Conditions	Operation in experiment
	With N-ethyl-N,N-diisopropylamine; In DMF (N,N-dimethyl-formamide); dichloromethane; at 20℃; for 1h;	To a solution of <strong>[629655-23-8]2-chloro-3-nitropyridin-4-ol</strong> (0.305 g, 1.75 mmol) in 10 mL DCM and 0.5 mL of DMF, was added DIEA (0.460 mL, 2.63 mmol) followed by [2-(chloromethoxy)ethyl](trimethyl)silane (0.370 mL, 2.10 mmol). The reaction was stirred at ambient temperature for 1.0 h, diluted with 100 mL of DCM, and washed with saturated sodium bicarbonate solution (2×). The organic layer was dried, concentrated and purified with 15%-100% EtOAc-Hexane on silica chromatography to give the title compound as white solid: 1H NMR (CDCl3) delta0.034 (s, 9H), 0.96-1.02 (m, 2H), 3.63-3.68 (m, 2H), 5.39 (s, 2H), 6.59-6.62 (d, 1H, 7.9 Hz), 7.51-7.54 (d, 1H, 7.9 Hz
