Two methods have been developed for preparing carbohydrate imidazole-l-sulfonates [68] (Scheme 6). The first, (method A) consists in allowing a partially protected sugar to react with 1.5 eq. of sulfuryl chloride in dimethylformamide (DMF) at —40°C in the presence... [Pg.130]

A series of monoalkylpyrazines has been chlorinated specifically at the 3-position with sulfuryl chloride in the presence of iV,V-dimethylformamide the nucleus of 2,6-dialkylpyrazines is also readily chlorinated (687,693). The reaction of isobutyl-pyrazine with phosphoryl chloride and phosphorus pentachloride gave 2-chloro-5-isobutylpyrazine in 25% yield (693). 2-Acetonylpyrazine and 2-phenacylpyrazine with aqueous potassium hypochlorite gave 2-dichloromethylpyrazine (694). [Pg.80]

Chloropyrazine with sulfuryl chloride at 65-150° gave 2,6-dichloropyrazine (772, 832) but 2-chloropyrazine with sulfuryl chloride in A(A -dimethylformamide at 70-75° was claimed to give a 62.5% yield of 23-dichloropyrazine (770,771). [Pg.103]

Attempts to brominate benzo[h]quinolizinium bromide (3) with liquid bromine gave an addition product (Section II,B). Bromination with bromine and aluminum bromide in dimethylformamide gave 1 l-bromobenzo[b]-quinolizinium bromide (137).71 Sulfuryl chloride and aluminum chloride under similar reaction conditions gave the chlorobenzquinolizinone (139), presumably from the 6,11-dichlorobenzquinolizinium salt (138).71 Without... [Pg.38]

This gives the 4-pyrimidone ring, which is converted into the 4,5-dichloro-6-(l-fluoroethyl)pyrimidine by the action of sulfuryl chloride in the presence of dimethylformamide (DMF) [68]. The chlorine on the 4-position of the pyrimidine ring is substituted with the side chain 2-[4-(trifluoromethyl)phenyl]ethylamine through a nucleophilic substitution reaction [63]. The side chain 2-[4-(trifluoro-methoxy)phenyl]ethylamine is prepared by chloromethylation of trifluorome-thoxybenzene followed by displacement of the chlorine atom with cyanide and reduction of the nitrile with Raney nickel [69]. [Pg.897]
