Sodium Azide → HCID 60207713, compound

Participants

Reaction Steps

A mixture of 2 (28.4 g, 90 mmol) and sodium azide (12 g, 184 mmol) in DMF (200 mL) was stirred overnight at room temperature. The reaction mixture was poured into ice-water (500 mL) and extracted with ethyl acetate (2×200 mL). The combined organic phase was washed with water (4×100 mL) and brine (50 mL). After removal of the solvent the crude product was passed through a silica gel pad (100 g) and washed with 1:2 mixture of hexane and diethyl ether. Concentration of the appropriate fractions gave 22.5 g of 3 as a pale yellow oil. LC-MS (M++Na) 300
