1.0 g (4.39 mmol) of methyl 2-tert-butyl-6-chloroisonicotinate [lit.: O. Isler et al., Helvetica Chimica Acta 1955, 38 (4), 1033-1046] and 3.8 ml (43.9 mmol) of a 40% strength aqueous methylamine solution were heated in a microwave oven (Biotage Initiator, with Dynamic Field Tuning) at 160° C. for 6 h. After cooling, the volatile components were removed on a rotary evaporator. The residue was taken up in 4 ml of semiconcentrated hydrochloric acid and once more heated in the microwave at 130° C. for 1 h. The product was then isolated directly by preparative HPLC (Method 12). Evaporation of the product fractions and drying of the residue under high vacuum gave 180 mg (92% pure, 18% of theory) of the title compound.
