200 g. (1.21 mol) of ethyl 2-methylnicotinate (Compound XI) and 1 l. of 40% aqueous methylamine were heated at 40° C. for 4 hours. The reaction mixture was stripped at reduced pressure to obtain the crude product (197.8 g.) as a thick oil which was distilled at 121°-133° C./0.18 mm. Hg. to give the product (175.8 g.), m.p. 69°-72° C.
