To a solution of 6.2 parts of 2-amino-3-pyridinemethanol in 23.5 parts of N,N-dimethylformamide there were added 6.8 parts of 1H-imidazole and 7.5 parts of chlorodimethyl(1,1-dimethylethyl)silane. The whole was cooled for 10 min in an ice-bath and was stirred overnight at room temperature. The reaction mixture was diluted with 100 parts of water and the product was extracted with 1,1'-oxybisethane (2x). The combined extracts were washed with water and NaCl (sat.), dried, filtered and evaporated, yielding 11.1 parts (93.1% ) of 3-[[dimethyl(1,1-dimethylethyl)silyloxy]methyl]-2-pyridinamine (interm. 1).
