반응 단계
Using the procedure of Example 1, the above-named compound is prepared from 5.0 g (40 mmol) of N-tert-butylhydroxylamine hydrochloride, 2.4 g (80 mmol) of paraformaldehyde, 9.0 g (41 mmol) of dibenzyl phosphite, 3.0 g (40 mmol) of sodium bicarbonate and 200 ml of tetrahydrofuran (THF) by heating at 55° C. for 14 hours. The residue is purified by recrystallization from a mixture of methylene chloride and hexane to give 9.2 g (64% yield) of a white solid melting at 106°-107° C.
