How is 3-(Methylamino)-1-propanol (CAS: 42055-15-2) typically synthesized?

3-(Methylamino)-1-propanol is typically synthesized via the reaction of methylamine with 1-propanol. Common methods include the Grignard reaction or the use of organolithium reagents. The reaction involves the substitution of the hydroxyl group of 1-propanol with a methylamino group, with good yield and selectivity. The process is usually carried out in anhydrous conditions to avoid side reactions.
