실험 절차
The title compound was prepared according to the procedure of example 4, step 1 starting from 2,6-dichloropyrazine (444 mg, 3.00 mmol), 3,5-difluorobenzyl alcohol (475 mg, 3.30 mmol) and NaH (55% in mineral oil, 144 mg, 3.30 mmol). The solid product was collected, washed with water, and dried to give 0.77 g (100%) of the crude product that was used directly in the next step. An analytical sample was recrystallized from diethyl ether/hexane: mp 70-71° C. MS m/z 257 (M+H)+. Anal. (C11H7ClFN2O) C, H, N.
