Benzenesulfonic acid, 4-amino-3-methyl

A second example is the yellow pyrazolone salt, Pigment Yellow 191 [129423-54-7]. It is the calcium salt of diazotized 2-amino-4-chloro-5-methyl-benzenesulfonic acid coupled with 3-methyl-1-[3 —sulfophenyl]-5-pyrazolone and provides a reddish yellow pigment for use in plastics applications. It shows very good heat stability and excellent resistance to nonpolar solvents and commonly used plasticizers (qv). It finds applications in high density polyethylene, polystyrene, and ABS, and shows satisfactory lightfastness. 

Methylation of 7-amino-l,2,3-triazolo[4,5-d]pyrimidine (8-azaadenine) (140) with dimethyl sulfate afforded the N-3 and N-9 methylated isomers 141 and 142, respectively, which upon further methylation with methyl iodide or benzenesulfonic acid methyl ester gave 3,7- and l,9-dimethyl-8-azaadeninium salts 144 and 145, respectively. Thermal decomposition of the dimethyl derivatives led to a transmethylation to give 6-methylamino-9-methyl-8-azapurine (143), whose methylation afforded 1- and 7-methyl-6-methylamino-9-methyl-8-azapurinium salts 146 and 147 (80ZOR2204) (Scheme 28).

Plant Chlorsulfuron is metabolized by plants to hydroxylated, nonphytotoxic compounds including 2-chloro-7V-(((4-methoxy-6-methyl-l,3,5-triazin-2-yl)amino)carbonyl)benzenesulfon-amide (Duke et al., 1991). Devine and Born (1985) and Peterson and Swisher (1985) reported that the uptake of chlorsulfuron in Canada thistle leaves ranged from 23 to 43% after 2 d. The uptake in roots is higher under slightly acidic conditions. Fredrickson and Shea (1986) reported 12% of C-chlorsulfuron was taken up in the roots at soil pH 5.9.

As seen in previous examples, the intermediate iminium salt produced by reductive amination need not be isolated, and reduction in situ is very common.52 A mixture of sodium cyanoborohydiide and ammonium acetate was used for the reductive amination of the aldehyde derived from acid hydrolysis of the dioxolane moiety in 1,94. In this example, the dioxolane moiety was hydrolyzed to release the aldehyde, which reacted with NaBH3CN/NH40Ac to produce an amine. The amine was then protected as its benzenesulfonate. The final product was methyl 9-amino-nonanoate benzenesulfonamide, 1.95 (20% overall yield).53...
