Guaiacol (1) reacts with ethylene oxide to give 2-(2-methoxyphenoxy)ethanol (2). Halogenation with thionyl chloride converts the alcohol group to a chloride, (3), which is used to alkylate benzylamine (4) to give the secondary amine (5). This forms a tertiary amine (7) when combined with 5-bromoacetyl-2-methylbenzenesulfonamide (6). The reduction of the carbonyl group with sodium borohydride produces (8) and catalytic hydrogenation removes the benzyl group, yielding amosulalol.
