Sodium hydride → HCID 22466491, compound

Participants

Reaction Steps

To a suspension of 48 mg (2.00 mmol) of sodium hydride in 4.0 mL of tetrahydrofuran was added 227 mg (1.00 mmol) of 2-(methylthio)-4-chloro-6-ethyl-1H-pyrrolo[2,3-d]pyrimidine and 478 mg (2.00 mmol) of 3-(trifluoromethyl)benzyl bromide. The reaction was stirred at ambient temperature for 18 hours then diluted with 30 mL of methylene chloride and washed with 20 mL of saturated sodium bicarbonate solution. The organic phase was dried with sodium sulfate and concentrated. The crude product was purified by flash chromatography (25 g silica, methylene chloride-heptane gradient 1:1 to 100:0) to provide 320 mg (83%) of 2-(methylthio)-4-chloro-6-ethyl-7-[[3-(trifluoromethyl)-phenyl]methyl]-7H-pyrrolo[2,3-d]pyrimidine as a white solid. nmr (500 MHz, CDCl3) δ1.31 (t, J=7.3 Hz, 3H), 2.58 (s, 3H), 2.59 (q, J=7.3 Hz, 2H), 5.44 (s, 2H), 6.31 (s, 1H), 7.18 (d, J=7.8 Hz, 1H), 7.41 (t, J=7.8 Hz, 1H), 7.45 (s, 1H), 7.54 (d, J=7.8 Hz, 1H)
