Using the same procedure as for 5-methyl-2-trimethylsilyl-4-furaldehyde but substituting 2-trimethylsilyl-4-furaldehyde (Compound 30) and methyl iodide with 2-triethylsilyl-4-furaldehyde (Compound 31) and 1-iodobutane, respectively, gives 5-butyl-2-triethylsilyl-4-furaldehyde (Compound 41). IR (neat): 1690 cm-1; 'HNMR (CDCl3):0.73 (q, 6H, J=8.4 Hz), 0.95 (m, 12H), 1.36 (p, 2H, J=7.5 Hz), 1.69 (p, 2H, J=7.5 Hz), 2.94 (t, 2H, J=7.5 Hz), 6.89 (s, 1H) and 9.91 (s, 1H) 13CNMR (CDCl3): 3.03, 7.17, 13.6, 22.2, 26.8, 30.4, 118.6, 122.5 158.4, 170.2 and 184.8. LRMS m/e (% abundance):266 (M+, 20) 238 (20) 237 (100), 87 (10) and 75 (20); HRMS exact mass calculated for C15H26O2Si 266.1702, found 266.1690.
